Best Valve Type For Flow Control

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.

Best valve type for flow control.

Most of the industrial applications in process industry uses globe valve as control valves. The best type of flow control valve to use depends on the design parameters of the application. Even though ball valves aren t the best device to control flow they are still commonly used because of their cost effectiveness. Pressure and temperature compensated fixed or variable flow control.

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. Above are general guidelines based on common application characteristics. Often arguments as to whether a linear or equal percentage trim is best are based on the theoretical inherent flow characteristics. Flow control valves are necessary components in a broad range of industries.

Latest in hydraulic valves. Here we will see how the consideration of the changes in process dynamics available valve pressure drop and control valve dynamics. Image via flickr by nalundgaard. These valves are known for being durable with excellent shutoff but don t always offer very precise control.

Valve rangeability is often stated as simply a deviation of the catalog flow characteristic from the theoretical characteristic. Let s talk about when it s okay to use a ball valve as a control valve. The flow control valves don t obstruct the fluid flow as a result of contamination.
