Best Valve Type For Flow Control

Let s talk about when it s okay to use a ball valve as a control valve.

Best valve type for flow control.

Latest in hydraulic valves. Most of the industrial applications in process industry uses globe valve as control valves. Valve rangeability is often stated as simply a deviation of the catalog flow characteristic from the theoretical characteristic. These valves are known for being durable with excellent shutoff but don t always offer very precise control.

Above are general guidelines based on common application characteristics. Determining which flow control valve type is best for your particular situation depends on a host of criteria but the most commonly used types include gate valves globe valves pinch valves diaphragm valves and needle valves. Here we will see how the consideration of the changes in process dynamics available valve pressure drop and control valve dynamics. Usually when someone say control valve then first valve comes in any engineer s mind is globe valves.

This anti clogging property is an important feature of flow control valves. Image via flickr by nalundgaard. The best type of flow control valve to use depends on the design parameters of the application. Flow control valves are necessary components in a broad range of industries.

The flow control valves don t obstruct the fluid flow as a result of contamination. They are very good in terms of control and coupled with actuator and characteristic of valve type globe valve can be used for wide range. Pressure and temperature compensated fixed or variable flow control.
