Quick Exhaust Pneumatic Valves
Quick Exhaust Pneumatic Valves increase pneumatic actuator speed by exhausting air directly at the cylinder rather than routing it back through the directional control valve.
Faster Cylinder Speed
Exhaust air is released close to the actuator for quicker movement.
Reduced Back Pressure
Shorter exhaust routing helps improve pneumatic performance.
Compact Design
Installs near the cylinder port with minimal system complexity.
Multiple Sizes
Port options support different actuator and flow requirements.
Product Overview
Quick exhaust valves are used to increase the speed of pneumatic cylinders by dumping the exhaust stream directly at the cylinder port instead of back through the control valve. The NQE is available in 4 sizes up to 1/2NPT and manufactured in aluminum with an anodized finish.

Frequently Asked Questions
What does a quick exhaust valve do?
It releases cylinder exhaust air directly to atmosphere near the actuator instead of routing it through the directional valve.
Why does this increase cylinder speed?
The shorter, less restrictive exhaust path reduces back pressure and allows air to leave the cylinder more rapidly.
Where should it be installed?
Install it close to the cylinder port for the best response and minimum exhaust restriction.
Can a silencer be fitted?
A suitable silencer may be installed when permitted, but it must be sized to avoid excessive back pressure.
How do I select the correct size?
Match the valve to cylinder flow demand, tubing size, operating pressure and desired speed.
Does it affect both cylinder directions?
A quick exhaust valve affects the cylinder port where it is installed. Two may be used when rapid exhaust is required in both directions.
What maintenance is required?
Keep the exhaust path clean and inspect the valve for contamination, leakage or restricted movement.
Can Pneuforce assist with sizing?
Yes. Provide cylinder bore, stroke, operating pressure, tubing and cycle requirements.
