The Clean-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 bubble-tight seal keeps devices in position. If pressure loss should occur, the valve prevents drifting. To release the seal, depress the manual override button or operate the pilot.

The Clean-Check® Valve is fully sealed for use in clean/sanitary environments without its function being affected. The valve is able to tolerate: dust, dirt, oil, grease, detergent, cleaning solutions and cutting fluids.

The Clean-Check® Valve has not been designed for use on vacuum, air over oil or high pressure applications.
