Brass Control Valve: The Ultimate FAQ Guide

Do you want to learn more about brass control valves?

This article answers common questions about the brass control valve. 

Learn the functions, benefits, and other factors to consider before purchasing a high-quality brass control valve.

What is a Brass Control Valve?

brass control valve

The brass control valve regulates pressure, flow, and temperature. 

This brass control valve functions according to the size pipe, working system pressure, flowing media, conditions, and other factors. 

What are the Types of Brass Control Valve?

Globe Valve

The globe valve uses proper controls with various flow characteristics. This valve is more expensive compared to other valve types.

Gate Valve

The gate valve is commonly used to shut off and isolate fluids. They are ideal for throttling operations.

Pinch Valve

This cost-effective valve type operates with corrosion or abrasive fluids. They work with air pressure falling in the sleeve.

Butterfly Valve

The butterfly valve utilized lesser space than other valves. This valve type is also suitable for fluid controls.  

It is accessible in immense diameters.

Ball Valve

The ball valve has two styles, the segmented and complete style. The segmented are formed for slurry flow controls while the full type operates for modulating service. 

Plug Valve

This control valve is less expensive than a ball valve but has similar characteristics. It is ideal for high flow rates at low-pressure drops.

What are the 2 Types of Brass Control Valve Motion?

Linear Motion

This motion alters the flow rate through the valve. 

The globe, pinch, and gate valve operate with linear motion.

Rotary Motion

Similar to the linear motion valve, the rotary motion is named according to the closure member shape. 

The rotary motion valve includes butterfly, plug, and ball valves.

How Do You Choose a Brass Control Valve?

There are numerous factors to consider when choosing brass control valves, such as:

  • The fluid to be controlled
  • Gravity range of fluid
  • Inlet pressure range to control valve
  • Flow range required
  • Outlet pressure range controlling valve
  • Zero flow pressure drop beyond the valve
  • Standard flowing condition pressure drop
  • Fluid temperature range
  • Fluid viscosity range
  • Appropriate noise level and measurement point
  • Size of outlet and inlet pipeline
  • Superheat degrees or flashing across the valve existence

Where is Control Valve Place?

The control valve should be placed at floor level or reachable from platforms.

This valve should be placed on similar equipment or pipelines.

How Do I Choose a Control Valve Size?

brass control valve

Make sure the control valve size performs between 20-80% open at the maximum required flow rate. 

In What Position Do You Install a Brass Control Valve?

Installing brass control valves is applicable at ay positions. 

But the most chosen installation is in a horizontal pipeline. 

The control valve actuator is in a vertical position.

What Do All Brass Control Valves Have?

There are three main parts of brass control valves including:

  • Body – This part consists of a globe, plug, ball, or butterfly and regulating elements. 
  • Actuator – This part is utilized to move valve regulating factors such as ball or butterfly.
  • Positioner – The positioner checks the degree of opening if it reaches a matter of wear and friction.

Some parts are bonnets, valve plugs, seat rings, and gaskets.

How Do You Install the Brass Control Valve?

  • First, make sure to clean up welding chips, scales, or any other strange materials where the brass control valve will be connected.
  • Make sure the fluid flow direction complements with connecting flanges flow laws.
  • Place the brass control valve with a vertically positioned actuator.
  • Be careful of gasket edges extruding. Make sure you choose the most suitable gasket material.
  • Do sufficient measures to prevent brass control valve immense force. Ensure tightening flange bolts to achieve your desired process.
  • After placing the brass control valve, remove the dust inside the air pipe using clean compressed air.
  • For the actuator removal, provide enough space over it.
  • Make sure the ambient temperature where you installed the valve does not surpass the actuator’s temperature range.
  • Examine the exact installed direction of the positioner and actuator pointer.

How to Inspect the Brass Control Valve Before Operation?

brass control valve

  1. Ensure the valve’s marked flow direction match up with the fluid flow direction.
  2. Make sure to secure tightening of the bolts and nuts.
  3. Confirm secured tightly of bonnet clamp bolts and yoke clamp bolts.
  4. Confirm the tightening of accessory devices like regulator valve, positioner, etc., are secured.
  5. Secured tightening and without air leaks bolts of stem connector.
  6. Confirm tightening of stem connector bolt that is connected to the actuator stem.
  7. Confirm undeformed actuator and valve stem. Ensure the valve doesn’t show symptoms of defects.
  8. Confirm smooth operation of brass control valve with its total lift scale limit.
  9. Make sure of the accurate compressed actuator spring.
  10. Confirm enough tightening of glands packing bolts.
  11. Lubricate the brass control valve if it uses asbestos packing.
  12. Ensure AUTO position nut of the handwheel and locked.

How to Do A Periodic Inspection and Maintenance of Brass Control Valve?
