FAQs

There are two main types of control valve designs, depending on the action of the closure member: sliding-stem (also referred to as globe or angle) or rotary (also called quarter-turn). Sliding-stem control valves use linear motion to move a closure member into and out of a seating surface. Whereas rotary control valves use rotational motion to turn a closure member into and out of a seating surface.

The pressure drop is the difference between the inlet pressure and the outlet pressure. It varies with flow. The pressure drop is usually measured in pounds per square inch differential or psid.
