D&R Brass Gate Valves

The brass gate valve is a multi-purpose shut-off valve mostly used in low-pressure, domestic water systems.

They are used for both above-ground and underground installation.

Gate valves are meant for either fully open or fully closed services; that is to say, they should not be used as regulating valves.


Water Pressure Test of Brass Gate Valve

Advantages of Brass Gate Valves

  • Have high corrosion tolerance.
  • They are tolerant to high temperatures.
  • Once opened, gate valves do not obstruct fluid flow hence minimum pressure flow.
  • Lead-free brass gate valves can be domestically used to control the flow of drinking water.
  • They can also be used as a venting valve, and as a low vacuum system valve.
  • Gate valves have dual flow directions; this means that it isn’t subject to flow in the medium’s direction. It is most suitable for pipelines where the medium changes the direction of flow.
  • The sealing performance is way better than a shut-off valve. This is because its opening and closing are more convenient than other valves.

Brass Gate Valve: The Ultimate Guide

In contrast to quarter-turn valves, gate valves do not open and close at 90-degree rotation of the valve system.

Gate valves require multiple turns of the valve stem in either the clockwise to open or the clockwise to close motion.

Brass gate valves are used to control the flow of water and gas mostly.

Although, it can also be used to control the flow of fuel and other petroleum products.


How a Brass Gate Valve Works

Brass gate valves work by lowering either a rectangular gate or wedge into the flowing fluid’s path.

Most of the gate valves are operated by a threaded stem, which connects the handwheel or actuator to the gate’s stem.

If the gate valve has a rising stem, its position can be determined by looking at the stem’s position.

When fully open, the gate valve has absolutely no obstructions in the flow of the medium.

This, in turn, results in little or no pressure drop.

Gate valves are not usually used to regulate flow because the liquid’s flow rate is not proportional to the opening of the valve.

A partially open gate valve may undergo some vibration that will force the valve to open fully.

Notably, a partially open valve may subject the gate and the seat to excessive wear.

Hence, it is advisable that you fully open the valve.

Ideal Uses of Brass Gate Valve

A gate valve is mostly used to shut off fluid flow completely.

Application of brass gate valve entirely depends on the medium you intend to pass and the purpose you want the valve to fulfill.

Commonly, brass gate valves are used in the following places:

  • Pipelines
  • Safety and firefighting equipment
  • Isolating valves
  • Treated water storage plants – the brass should be lead-free.
  • Piping systems
Components of Brass Gates Valves

For the brass gate valve to function efficiently, it has the following components that work harmoniously to cut off or allow fluid flow.

Parts of Industrial Brass Gate Valve

Parts of Industrial Brass Gate Valve

  • Body made of ductile iron or brass
  • Seat ring made from brass
  • Wedge from ductile iron
  • Wedge ring from brass
  • Wedge nut also made from brass
  • The stem made of stainless steel
  • Bonnet gasket made of rubber
  • Bonnet made of ductile iron
  • Stem collar made from carbon steal
  • Thrust washer (PTFE)
  • Gland Flange Gasket made from rubber
  • Stem sealing made from rubber
  • Gland flange made from ductile iron
  • The hand wheel (GI)
Design Classifications of Brass Gate Valves

Gate valves are classified based on three components namely bonnets, gates, and stem design.

The classifications according to the three components are discussed in detail below.


First, the screwed bonnet has the simplest design and is widely used in fairly cheap valves.

The most popular bonnet type is the bolted which is adopted by many gate valves.

To seal the joint between the body and the bolted bonnet, you will require a gasket.

If you are looking for a lightweight bonnet, then the welded bonnet is your go-to.

These bonnets are lightweight compared to bolted bonnets.

Importantly, they are only used where there are no plans for disassembly.

Lastly is the pressure-sealed bonnet which is applicable in both high pressure and temperature.

To achieve a greater force on the gasket, the body’s cavity pressure should be high.

Stem Design

Brass gate stem valve, similarly to other valves, can be classified in terms of the rising of its stem.

This type of classification is straightforward, you simply classify them whether the stem is rising or is constant.

To be classified as a rising stem valve, the stem ought to rise above the handwheel as you open the valve.

The reverse applies when closing the valve.

The below diagram best explains a rising stem valve.

Rising Stem Brass Gate Valve

Rising Stem Brass Gate Valve

A non-rising stem (insider screw valve) has an internally threaded valve disc.

As such, the disc/gate moves up the stem when the valve is opened.

Here, the stem will not move upwards.

Insider screw valve is used where the flow medium is not corrosive, and there is limited space for the stem to rise.

Otherwise, if the medium can corrode the stem material, the Outside Stem and Screw Typevalve should be used.


Classification by gates/wedges/disc is the broadest.

A gate valve can either have a solid taper wedge, flexible wedge, or parallel discs valves/ split wedge

i. Flexible Wedge

This is a solid piece disk with a cut on every side of the perimeter.

The cut determines the flexibility of the wedge.

For example, a deep, wide cut gives more flexibility but reduces the wedge’s strength.

As such, a narrow, shallow cut around the perimeter is preferred.

However, the flexible wedge design is prone to corrosion since the fluid constantly collects on the disc.

Below is an image of a flexible wedge gate valve.

ii. Solid Wedge

Unlike the flexible wedge, this type of gate valve has a solid wedge (not cut).

This type of valve is widely used for its simplicity and durability.

Its strength makes it best suitable for turbulent conditions.

However, this type of wedge is prone to thermal lock in high temperatures since it is not flexible.

iii. Parallel Discs/Split Wedge

As the name suggests, this type of valve has two split wedges held together.

These parallel wedges are spring-loaded to maintain constant contact with the seats.

This results in a bi-directional sealing by the discs.

They are commonly used at both high and normal temperatures to control noncondensing liquid and gas flow.

These valves are also not susceptible to thermal binding.

Split Wedge Brass Gate Valve

How Plastic vs Steel vs Brass Bodies for Gate Valves compare

Brass valve consists of copper alloy (copper and zinc) and at times other metal compounds.

This implies that it is way stronger than plastic.

Due to its various compounds, it is corrosion-resistant, unlike the plastic valve.

Brass can also tolerate more heat than the plastic valve, making it a more preferable choice for domestic plumbing systems.

The most prevalent difference between stainless steel and brass valves is in their welding.

The brass valves are more easily welded compared to the former.

While brass is an alloy of copper, stainless steel majorly comprises carbon and iron.

However, other compounds such as nickel, chromium, manganese, or molybdenum can be added to form low alloy steel.

Steel is a durable and resistant metal.

Steel can work in high temperatures compared to brass and also lasts longer.

Stainless steel is more convenient for high temperatures and high-pressure industrial piping.

In terms of cost, stainless steel valves are the most expensive compared to brass and plastic valves.

This fact will greatly influence your choice depending on your budget.

The FDA does not warrant the use of brass valves in food industries unless they are certified to be lead-free.

In the recent past, most brass alloys contained lead, making them unsuitable for food processing industries.

However, currently, there are more lead-free brass materials available in the market.

Difference between Brass Gate Valve and Brass Ball Valve

Both brass gate valves and brass ball valves have different specifications that make them unique to specific functions.

An in-depth look at the difference is discussed in the below subtopics.

Shut-off speed

The ball valves are sometimes referred to as shutoff valves.

They are most convenient for the immediate shut-off of flow, however, gate valves are incapable of immediate redirection.

Only a quarter-turn of the actuator is required to shut the ball valve.

Conversely, the gate valve handwheel goes a full 360 degrees turn to close the valve.


Gate valves are prone to leakages compared to ball valves.

Ball valves provide a tight seal even after a lengthy period of usage.


Additionally, a gate valve has only two ports, while a ball valve can have more than two ports.

Flow Capacity/Rate

The gate valves have a large flow capacity compared to the ball valve.

The gate valves are offered in large diameters.

Once opened, the gate valve does not bar the flow.

This is different in ball valve, where the flow can be interfered with depending on the opening’s size on the rotary ball.


Cost-wise, ball valves are more expensive than gate valves.

However, keep in mind that the cost disparity is not determined by functionality but rather the architecture employed in building the valve.

Water Hammering

Water hammering is more prominent with the ball valves because of the fast opening and closing.

The brass gate valve has a slow opening and closing that reduces the risk of water hammering.


The brass ball valves are quite durable and less prone to damage.

While opening or closing the turn, you only make a 90 degree turn.

This is a minimal turn which reduces any wear and tear that might result from frequent rotation..

On the other hand, brass gate valves are relatively less durable for the following reasons.

First, their stems are prone to corrosion.

Secondly, the constant 360 degrees turns will result in the stem’s wear and tear if not properly oiled.

Installation Space

The installation space required by the brass ball valve is relatively more.

This is because of the quarter turn handle than the brass gate valve, which has a raised handwheel.


Both the ball and gate valves are best suited for low-pressure applications.

Although for high-pressure application, a gate valve is more suitable.

The ball valve may cause water hammer because of its fast opening and closing.

Thermal Expansion Rate of Brass Gate Valves

The thermal expansion coefficients at 20 degrees Celsius of a brass gate valve are 19-11 fractional expansion per degree.

How NPT Threaded and T-clamp End Connections for Brass Gate Valves compare

NPT is a U.S. standard for tapered threads used on threaded pipes and fittings.

A taper thread offers a tight pull which results in a fluid-tight seal.

Conversely, the T- clamp has connections that tighten around the flanged ends and squeeze them together with a gasket in between.

Maximum Operating Temperatures of Brass Gate Valves

The maximum temperature that a brass gate valve can operate under is 150 degrees Celsius.

Pressure Limit for Brass Gate Valves

The pressure limit or range for a brass gate valve is between 0 to 25 BAR.


Brass Gate Valve

Brass Gate Valve

Recommended Pressure Rating for Brass Gate Valve

The brass gate valve has a brass body with a metal seat and PTFE gland.

It has a pressure range of 0 to 25 BAR.

Difference between PN 16 and PN20 Brass Gate Valve

The PN 16 brass gate valve has a full bore; it also has a rotating non-rising stem.

This brass gate valve type has an inside screw stem.

It is a single wedge disc and also has female/female BSP cylindrical ends and is mostly used for water distribution.

The temperature range is -10 to +80 degrees Celsius.

The maximum amount of pressure that the PN16 can withstand is 16 bars; making it not suitable for firefighting networks.

For the PN20 brass gate valve, it can withstand the pressure of up to 20 bars.

It works within a temperature range of between -20oc to 120oc, a slightly higher range than the PN16.

As you have noted, the PN 16 and PN 20 are the pressure ratings for the different types of brass gate valves.

Benefits of Seal O-rings for Brass Gate Valves

The O-rings offer a tight seal in various temperature and pressure ranges.

O-rings can be made from materials such as silicone, nitrile rubber, fluorocarbon, polyurethane, silicone, and a number of other elastomers.

As a sealing component, you will get the following benefits if you seal your brass gate valve using an O-ring.

  • O-rings are tolerant to a range of temperature and pressure.
  • It is easy to service O-rings since they require no smearing or re-fastening.
  • You do not require special tools to install them.
  • O-Rings have a symmetrical circular cross-section, meaning you can use them in any direction.
  • O-rings are reusable.
  • Depending on the material used to manufacture the O-ring, they are fairly durable.
  • Failure of O-ring is easily identifiable since it occurs gradually.
  • The composition of O-rings makes them highly resistant to aggressive environmental conditions and chemicals
  • Installation of O-rings require less tightening or torque, hence results to little or no structural damage of the brass gate valve
Available Size Options for Brass Gate Valves

The Brass gate valves come in different shapes and sizes.

You will choose a size depending on what meets his or her demands.

The sizes include: ¼’’, 3/8’’, ½’’, ¾’’, 1’’, 1-1/4’’, 1-1/2’’, 2’’, 2-1/2’’, 3’’, and 4’’

Benefits of ANSI Brass Gate Valves

Brass gate valves have a number of features that make them suitable for different conditions.

Some of the ANSIbrass gate valves features that double up as their benefits include:

  • 200 WOG meaning it is suitable for cold water, oil and gas.
  • 125 WSP meaning it is steam saturated.
  • A full-port design for an efficient water flow
  • It has a screw-in bonnet – non-rising stem and a solid wedge
  • The ends are NPT threaded for tight sealing.
  • It has a Cast iron handle which is durable.
  • Each of the valves is individually air tested underwater for efficiency.
  • The ANSI brass gate valve is good for diesel fuel.
  • The brass gate valve has a temperature range of 32-320F, making it efficient in relatively high temperatures.
Difference between ANSI and NSF Standards for Brass Gate Valves

The American National Standards Institute (ANSI) outlines the US standards in the valves industry.

The ANSI standards are majorly industrial oriented.

For this reason the standards are a guideline for brass gate valves with lead.

In contrast, the National Sanitation Foundation (NSF) standards are major to the use of valves in domestic and food processing industry.

As such, the NSF standards are greatly tied to lead-free brass gate valves.

The two standards can be applied hand in hand. For example, a NSF/ANSI 61 mark on a valve implies that the valve has been approved in the transmission of potable water.

Available Options for Brass Gate Valve Hand wheel Actuation

The four major options we provide for brass gate valve hand wheel are:

  • Manual actuator – Which raises or lowers the brass gate valve’s stem through human assistance.
  • Electric actuator – Which raises or lowers the stem of the brass gate valve using force from an electric motor
  • Pneumatic actuator – Which raises or lowers the stem of brass gate valve using the force compressed air.

Brass Gate Valve Pneumatic Actuator

Brass Gate Valve Pneumatic Actuator

  • Gearbox actuator – Incorporated in either a pneumatic and electric actuator to add the feature of manual control if the primary actuator fails.

The gearbox actuator is more advantageous among the four options.

This is because it incorporates either pneumatic or electric actuator, plus a manual actuator.

Comparison between Manually Operated Brass Gate Valve and Automated Brass Gate Valve

Manual actuation of a brass gate valve involves direct physical contact with the hand wheel, lever, or gear operator.

On the other hand, the automated actuation uses either air pressure, electricity, or hydraulic pressure controlled by flow conditions, monitoring systems.

Or any other means that does not involve physical contact with the valve.

Some valve actuators have switches or other ways of remotely monitoring the position of the valve.

The manually operated hand-wheel offers more control while opening and closing the valve than the automated valve.

However, it can be a bit challenging to operate the manual hand-wheel, especially under high-pressure conditions.

In such conditions, it requires a lot of strength to operate, unlike the automated valve that only requires switching on.

The automated valves are prone to mechanical breakdown or might be dysfunctional in cases where there is power shortage.

This does not apply to the physically operated valves.

Importance of FM Approval for Brass Gate Valve

The FM approval certifies products and services with a special focus on loss prevention.

An FM Approval certification is an indication that the product has met meticulous loss prevention quality standards, performance, and quality integrity.

The FM approval is very important for Brass gate valve because it is one way to get customers to have confidence in your product and service.

The FM approval mark is recognized and known worldwide.

Best Interior Coating Option for Brass Gate Valves

Our brass gate valves have a highly wear-resistant internal enamel lining which can withstand abrasive media.

It also forms a chemical bond with the casting. This hinders any occurrence of creeping corrosion.

According to DIN 3476 part 1, EN 14901, and GSK guidelines, the required corrosion protection is an external and internal epoxy coating.

Some gate valves have an external PUR coating according to EN 102 type 2, class B.

These are mostly developed for use in steel gas pipelines with cathode protection.

Quality Assurance Standards Brass Gate Valves should conform to

Below are some quality standards most gate valves used to control the flow of fluids conforms to:

GIS / BIS V7-1:2013

The Gas Industries Standards (GIS) V7-1 has the below requirements for the brass gate valves:

  • The valves should be able to operate in temperatures within a range of -20 oC to 60 o
  • The Maximum Operating Pressure (MOP) for valves used as line valves should be 16 bar while those for construction valves should be 7 bar.
  • Each valves MOP has to be specified in the purchase order

EN 13774

These standards apply to valves with a maximum operating pressure less than one or equal to 16 bar.

The EN 13774 prevails in cases where the DIN EN 13774 is contradictory.


How to Mount Brass Gate Valves

Brass Gate Valve Application

Brass Gate Valve Application

Below is a guide on how you will mount your brass gate valve right from the storage to the point the gate valve will be functional.


Before installation, the valve and fittings should be stored in a dry and secure place to protect them from extreme weather conditions or exposure to sand.

The valve and the fittings should be left in the original packing.

Handle the product with care, do not drag or drop on the floor or any other surface.

Cleaning of the Valve and Pipes

Before starting the installation process, you should clean the pipes with compressed air or water.

You are required to check for welding spatters or any metal chips that, by any chance may have attached themselves to the valve’s sealing surface.

Importantly, also ensure that the pipes you intend to fit the brass gate valve are clean.

Dimensions and Alignment

Check that the pipes’ dimensions align with the brass gate valve.

You should make sure that the downstream and upstream pipes are well aligned.

Any mistake in the dimensions may result in potential future leakages.

Worse off it can cause damages to the entire piping system and the brass gate valve.

Expansion Joints

For pipes conveying heat transfer fluids, you should look out for dilation compensation with the aid of specialized equipment, namely, loops and expansion joints.

The absence of these may lead to mechanical ruptures and blockage of valves.

Install the spacing bolts cautiously, making sure you do not damage the valve seat.

Adjust the two flanges’ face to face, so there is space when the piping is spread open.

That is to say; there should be enough space to slip the valve in or out for regular service.

Mounting Direction

A good number of devices do not exactly have symmetrical functioning.

Consequently, you should adhere to the mounting direction engraved or stamped on the body.

Ensure that you place the valve correctly according to the direction of the fluid flow.


While installing the valves on the pipes, you ought to use adapted lifting devices such as the bridge crane, forklift, or hoist.

This is very important because it is necessary to align the valve correctly while installing it.

The valves can be installed in any orientation; however, it is advisable you install the valve upright for ease of access to the wheel hand.


Those valves that significantly have more weight than the pipes solidity must be provided some additional support independently from the pipes.

It is also important to note that the valves should not serve as support for the pipes since they have to support themselves.

In case any of these isn’t considered, it might result in leakages, blockages, or damaging the valve.

Once the pipes are centered, you should make the bolts’ quick insertion to give the valve a resting platform, consequently preventing the valve from falling.


Once you have gotten to this stage, you are almost done with the installation process.

It is highly advisable you use the right tightening torque for the flanged and threaded valves and their fittings to avoid breakage.

Insufficient tightening may lead to leakages, while over-tightening can block the valve or result to mechanical ruptures.

The coupling torques are indicated on every product.

Tighten the bolts one at a time, in stages.

This way, even pressure will be applied, resulting in the creation of a seal between the gasket, valve, and flanges.
