Best valve type for flow control.

Valve rangeability is often stated as simply a deviation of the catalog flow characteristic from the theoretical characteristic. Usually when someone say control valve then first valve comes in any engineer s mind is globe valves. 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.

Here we will see how the consideration of the changes in process dynamics available valve pressure drop and control valve dynamics. Even though ball valves aren t the best device to control flow they are still commonly used because of their cost effectiveness. 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. Let s talk about when it s okay to use a ball valve as a control valve.

These valves are known for being durable with excellent shutoff but don t always offer very precise control. Reduced fluid consumption low cost reliability and improved performance are the main advantages of the flow control valve. 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. 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. Flow control valves are necessary components in a broad range of industries.
