Best Valve Type For 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.

Best valve type for flow control.

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

Even though ball valves aren t the best device to control flow they are still commonly used because of their cost effectiveness. Valve rangeability is often stated as simply a deviation of the catalog flow characteristic from the theoretical characteristic. Latest in hydraulic valves. Let s talk about when it s okay to use a ball valve as a control valve.

Pressure and temperature compensated fixed or variable flow control. 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.
