Valves • Pneumatic Valves

Pneumatic valves are used in a variety of applications including high speed combustion engines including high performance race engines.

Pneumatic valves use pressurized gas to affect and regulate the mechanical motion of high speed combustion engines. A type of pneumatic valve, a pneumatic solenoid valve is a switch for routing air to any pneumatic device, typically an actuator. These valves are commonly used to control a piston or other linear actuator, and feature one, two, or, three-output ports.
