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.

These valves are known for being durable with excellent shutoff but don t always offer very precise control. 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. Image via flickr by nalundgaard.

Even though ball valves aren t the best device to control flow they are still commonly used because of their cost effectiveness. Often arguments as to whether a linear or equal percentage trim is best are based on the theoretical inherent flow characteristics. This anti clogging property is an important feature of flow control valves. Most of the industrial applications in process industry uses globe valve as control valves.

Above are general guidelines based on common application characteristics. Latest in hydraulic valves. Reduced fluid consumption low cost reliability and improved performance are the main advantages of the flow control valve. The flow control valves don t obstruct the fluid flow as a result of contamination.

Valve rangeability is often stated as simply a deviation of the catalog flow characteristic from the theoretical characteristic. 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.
