Directional-control valves are common in pneumatic systems. They control compressed-air flow to cylinders, rotary actuators, grippers, and other mechanisms in packaging, handling, assembly, and ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

Directional-control valves are vital in any pneumatic circuit, directing or blocking airflow to control the speed or sequence of operations. One method of classifying directional-control valves is by ...

Refrigeration control valves for industrial refrigeration systems have been an important system component since the 1920s. When a control valve fails, the result can be as significant as a more costly ...
