Description
Pneumatic Quick Exhaust Valve – Q Series
The Q Series pneumatic quick exhaust valves are designed to rapidly vent compressed air directly from pneumatic cylinders, significantly increasing actuator speed while reducing back pressure and improving overall system efficiency. Suitable for compressed air and inert gas systems, these high-performance exhaust valves are widely used in industrial automation, factory machinery and pneumatic control applications.
By exhausting air directly at the cylinder port rather than back through the directional control valve, the Q Series delivers faster cylinder movement, shorter cycle times and improved machine productivity. The compact aluminium alloy body allows direct installation onto cylinder ports for maximum performance.
Why Choose the Q Series?
✓ Rapid cylinder exhaust for faster cycle times
✓ Reduces exhaust back pressure
✓ Improves pneumatic actuator response
✓ Compact aluminium alloy construction
✓ Direct cylinder port mounting
✓ BSP, NPT and Rc thread options
✓ Suitable for compressed air and inert gases
✓ Proven industrial reliability
