Best Valve Type For Flow Control

Often arguments as to whether a linear or equal percentage trim is best are based on the theoretical inherent flow characteristics.

Best valve type for flow control.

Even though ball valves aren t the best device to control flow they are still commonly used because of their cost effectiveness. Flow control valves are necessary components in a broad range of industries. 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. Usually when someone say control valve then first valve comes in any engineer s mind is globe valves.

Valve rangeability is often stated as simply a deviation of the catalog flow characteristic from the theoretical characteristic. Image via flickr by nalundgaard. Here we will see how the consideration of the changes in process dynamics available valve pressure drop and control valve dynamics. 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. The flow control valves don t obstruct the fluid flow as a result of contamination. Latest in hydraulic valves.

The best type of flow control valve to use depends on the design parameters of the application. Pressure and temperature compensated fixed or variable flow control. Most of the industrial applications in process industry uses globe valve as control valves.
