Pneumatic Quick Exhaust Valves

Pneumatic quick exhaust valves are used alongside pneumatic cylinders to boost speed and reduce backpressure. Incorporating these valves enhances overall system efficiency and can allow for smaller cylinder sizes. Pneumatic Resources supplies a variety of premium valves from the leading brand, SMC.

How Does a Pneumatic Exhaust Valve Work?

Quick exhaust valves function by routing compressed air from the cylinder directly to the atmosphere rather than allowing it to flow back through the valve. This mechanism increases the extension speed of the actuator piston rod. For optimal performance, exhaust valves should always be installed directly on the vent side (exhaust port) of the pneumatic cylinder.

Applications for Quick Exhaust Valves

Quick exhaust valves are widely used in various high-pressure pneumatic applications. Their capability to handle very high pressures makes them ideal for industries such as oil, gas, chemical processing, and automation.
