Single Check Pneumatic Check Valves
Aladco single check vales traps air in one-side of cylinder or actuator with the pilot operation able to relieve the pressure of the cylinder or actuator, which can also be accomplished by our patented manual override button.
The Nu-Check® valve, designed specifically for pneumatics, is a patented Aladco® product. It was the first check valve on the market with both manual and pilot release capabilities. The unique bubble-tight seal keeps devices in “checked” position.
The Clean-Check® valve, designed specifically for pneumatics is a patented Aladco® product. It is a normally closed check valve that can be overridden manually or by air piloting to allow two-way flow.
The Equa-Check® valve, designed specifically for pneumatics, is a patented Aladco® product. It has a normally engaged air pilot which creates an internal pressure balance between the IN pressure and the PILOT pressure, which makes it ideal for balancing and tensioning applications.
