Humphrey Super Quick Exhaust, Check & Shuttle Valves

Humphrey Super Quick Exhaust Valves are known worldwide for their unrivalled response speed, extremely high flow and long service life. These valves considerably improve the performance of your pneumatic cylinders and actuators. That is why industry chooses Humphrey when speed and reliability are crucial for the production process.

Super Quick Exhaust: maximum acceleration

Humphrey Quick Exhaust valves vent compressed air to atmosphere directly at the cylinder. This means the air does not have to flow all the way back through the main valve and the tubing.

• Unique shuttle design: Unlike competitors' flat discs, Humphrey uses a specially shaped rubber shuttle (bat wing). This design provides a more direct response and a much larger flow capacity.
• Increased cycle speed: By eliminating back pressure directly, you considerably speed up the movement of your cylinders.
• Noise reduction: You can easily fit a muffler on the exhaust port to lower the noise level in your work environment.

Shuttle and check valves for logic control

In addition to quick exhaust, this series offers essential components for your air circuit:

1. Shuttle valves (OR logic): These valves pass air from one or the other inlet to one common outlet. That makes them indispensable for systems you want to operate from multiple locations.
2. Check valves: These components allow air flow in one direction only. They also guarantee that the pressure in a specific part of your system is maintained, even if the supply fails.
