Types of Brass Valve You Have to Know Today
Brass valves are unique types of valves made ideally of brass (the combination of zinc and copper alloy). These types of valves are used mostly in industrial piping and plumbing systems. There are different types of brass valves. Knowing them helps in making the right choices. Read on for more information.
Types of Brass Valves based on Design
1. Brass Ball Valve
Brass ball valves are mainly used in cutting off or turning off mediums within pipelines. They can also be used in controlling and directing liquid.

How This Type Works
This type of brass valve uses a ball in the control of flowing water. Its ball comes with a hole. This hole makes it possible for water to flow whenever valves are opened. When its valve is closed, it closes. So, water or any fluid isn’t able to flow through it. It is advisable to use led free brass ball valves to ensure safety.
Applications

9. Brass Non Return Valve
A brass non return valve is a type of check valve that is spring loaded. It is designed to be used in liquid systems where flow is necessitated to be in a single direction without returning.
How It Works
They work by permitting media to move through them in a single route or way. They come designed with two openings. One opening is for media to enter while the other is for it to exit. Brass non return valves do not require external controls to work, on their own, they can work perfectly.

Application
- Seen used mostly in pumping stations.
- Used with mixing looks in cooling as well as heating systems. This helps for the right operation.
- Installed into domestic water setups to ensure backflow doesn’t happen.
10. Brass Foot Valve
A brass foot valve is a type of non-return valve that is also spring loaded but comes with plastic and stainless-steel strainer in full.
Working Principle
Water flows upwards when the brass foot valve is opened. This is mostly due to the pressure coming from the liquid. The pressure moving upwards stops when the pump is shut off. In such a case gravity does its work to ensure the water left in the pipe goes down and back into its well.

Application
- Used in pumping installation
- Irrigation systems
- Car washing systems
- Wells
- Pools and ponds, etc.
11. Brass Shut Off Valve
Brass shut off valves are designed to ensure water flow as well as the flow of other materials are controlled. This is achieved with full off or on features or at a flow level that is static. This valve makes it possible for compressed air where pneumatic uses are concerned to be controlled safely.

Working Principle
Brass shut off valves are used most of the time in connection with safety. When installed, all that is required is for it to be turned on and off depending on the need at a time. Turning it on means allowing for liquid to flow through and turning it off shuts the flow.
Applications
Some industries they are used include:
- Fuel units for control and smooth flow of fuel.
- Water piping installations and plumbing works.
- Pneumatic applications.
12. Brass Needle Valve
Brass needle valves are designed mainly for gas and fluid metering. This is done by the orifice size being adjusted. They come designed with an O-ring seal to get rid of valve maintenance.
How It Works

Types of Brass Radiator Valves
- Smart
- Thermostatic
- Manual
Different Shapes of Brass Radiator Vales
- Corner
- Straight
- Angled
How Does It Work?
The brass radiator works mostly based on its setup. Based on how it is installed, it can adjust water flow going into the radiator from boiler. As heating takes place in the room, there is a capsule inside the valve head which opens. When this happens, it moves a pin within the body which makes it close. This means less hot water is received into the radiator.
Applications
- For radiators
- Specific plumbing systems
18. Brass Isolation Valve
Brass isolation valves are used in shutting off water from specific rooms or appliances. So, turning off the whole water system is not needed. It is also called the membrane valve.

Types of Brass Isolation Vales
- Ball
- Gate
How Does It Work?
They work by isolating water heating systems that are tankless from the rest of the property. They work automatically when installed by stopping media flow process to a specific location. This is required when there is the need for some level of safety or maintenance.
Applications
- Residential heating systems
- Plumbing setups
- Pipping systems
19. Brass Schrader Valve
Brass Schrader valves known as well as American valves come with valve stems. Into these stems, valve cores (poppet valves aided by springs) are threaded. This makes them ideal to be used in all car or vehicle tires as well as bicycle tires with wider rims.

How Does It Work?
Shells and pins or even springs are used in keeping the pressure of air in or out. In settings of HVAC, this valve ensures that the refrigerator always has air out of it.
Applications

How Does It Work?
They work by screening all pipelines before control valves as well as prevent contaminates from reaching areas of the pipeline where they can cause major damages. They work automatically.
Applications
- Plumbing
- Industrial
- Commercial
- Water tanks
22. Brass Plug Valve
Brass plug valves are valves that come with conically tapered or cylindrical plugs. These can be rotated or moved within valve bodies to ensure flow is well controlled.
How Is It Used?
The plugs in brass plug valves come with one or even more empty passageways. These passageways go sideways through these plugs. This is done to ensure fluid is able to flow through plugs when valves are open.

Applications
- Water process piping
- Air supply systems
- Low air pressure services
23. Brass Bypass Valve
To ensure that antifreeze is saved water heaters need to be bypassed. This is where brass bypass valves come in. When this valve is installed, it is easy for water heaters to be drained ahead of the winter seasons.
How Does It Work?
Brass bypass valves are kept closed with brass isolation valves kept open during operation. Therefore, flow is moved or goes through brass isolation and control valves without any going through the brass bypass valve. This means brass bypass valves work in some way with brass isolation valves to achieve its results.

Applications
- Water filtration systems
- Heating systems
- Water storage systems, etc.
24. Brass Backflow Valve
Also called a backwater valve, brass backflow valves are installed in sewer lines and designed to permit sewage or liquid flow only in a single direction which is out of the property. When there is heavy rainfall, the tendency of overwhelmed sewer lines creating issues is high. However, this valve works by ensuring there is no sewage flowing back into the property at any time.
Working Principle
Within the brass backflow valve, there is a small flap. This flap is mostly open to allow water to go out of the property as well as makes it possible for other sewer gases to go out. On each side of this small flap there are small floatation devices. So, when sewage or water begins to flow backwards into the property, these devices initiate a lifting up and closing of the flap.

This prevents anything from coming into your property. When there is no more threat like water coming in backwards, gravity allows the small flap to move back into its position of being open to go on with its main duty.
Applications
- Used in plumbing systems for residential and commercial properties.
- Gas industry
- installed in basement piping systems, etc.
25. Brass Service Valve
Brass service valves are valves used in splitting air conditions to link both indoor and outdoor units. It is also used in some other refrigeration and cooling systems.
How It Works
Where HVAC use is concerned or for these systems, brass service valves are located closest to the compressor unit outlet. Due to that, this valve permits the momentary isolation of the compressor from other systems as well as connects its refrigerator charge without having to interrupt the smooth working of the entire system.

Applications
- Air conditioning systems
- Refrigeration systems
- Other cooling systems, etc.
26. Brass Water Valve
Brass water valves are designed to partially, or wholly restrict water flow through pipelines. These valves come in different styles and types and based on where and how they will be used, their sizes even differ.

Different Types of Brass Water Valves
- Brass gate valve
- Brass stop valve
- Brass check valve
- Brass ball valve
- Brass pressure relief valve
- Brass butterfly valve
- Brass supply stop valve, etc.
How It Works
Brass water valves work by opening to allow water to flow and closing to end the flow.
Applications
- For plumbing works
- In pipeline laying
- Car wash settings
- Ponds, and pools
- Wells and water tanks, etc.
27. Brass Gas Ball Valve
Brass gas ball valves are designed to use hollow, perforated balls as their element of closure even as they ensure the smooth flow and regulating of vapor, gas, air, and oil. Both residential and commercial settings depend on these valves to deliver liquified petroleum gas and others.
How It Works
The ball in the brass gas ball valve has a port or home in the middle. This makes it difficult for gas to flow out of hand or with much more pressure that required. The valve gets closed when the ball is moved to the flow path. So, gas or any other thing is not able to flow.

Applications
- In oil industries
- Found in gas appliances and equipment
- Industrial gas systems
- Medical gas systems, etc.
28. Brass Air Valve
Brass air valves are valves with the one-way mechanical design used in maintaining high level of stability where pipeline pressure is concerned. When there is a lot of air in pipes, it can restrict the flow of fluid. This is why brass air valves are installed to ensure excess air is vented.
How It Works
A decrease in the pressure of pipelines is needed from time to time. So, the brass air valve opens up to allow bottled up air out of pipes. After air is vented, it closes back. This is because the pressure balance has been restored.

Types of Brass Air Valves
- Automatic
- Kinetic or Double Acting
- Combined or Triple Effect
Applications
- For wastewater pumping stations
- Water hammer protection
- Air relief protection
- Piping systems
- Sewage pipelines
