The Nu-Check© Valve, designed specifically for pneumatics, is a patented ALADCO® product. It is the only check valve on the market with both manual and pilot release capabilities. The unique bubble - tight seal keeps devices in "checked" position. If pressure loss or fluctuation should occur, the valve prevents drifting. To release the seal, depress the manual override button or operate the pilot.
