Best valve type for flow control.

Usually when someone say control valve then first valve comes in any engineer s mind is globe 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. 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. 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.

Here we will see how the consideration of the changes in process dynamics available valve pressure drop and control valve dynamics. This anti clogging property is an important feature of flow control valves. Latest in hydraulic valves. Valve rangeability is often stated as simply a deviation of the catalog flow characteristic from the theoretical characteristic.

Reduced fluid consumption low cost reliability and improved performance are the main advantages of the flow control valve. 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. Flow control valves are necessary components in a broad range of industries.
