Aladco® single pneumatic check valves trap 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.
Nu-Check®
The Nu-Check® 3-series 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.
Clean-Check®
The Clean-Check® 5-series 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 valve is fully sealed for use in sanitary or harsh/dirty environments.
