Overview:

The Aladco Clean-Check valve is a normally closed check valve that can be either overridden manually or by air piloting to allow two-way flow. The tightly sealed Clean-Check valves are used on pneumatic devices to stop motion upon loss of air pressure and prevent the device from drifting. The Clean-Check valve, being vent free, is designed specifically for pneumatic applications used in clean/sanitary environments. The Clean-Check valve is also highly tolerant of external dust, dirt, oil, grease, detergent, cleaning solutions, and cutting fluids. The unique bubble-tight seal keeps devices from drifting toward the “checked” position in the event of pressure loss or fluctuation. To release the seal, press the manual override button or operate the pilot. Aladco highly recommends the use of spring centered 3 position 5-way centered vented valves for directional control with the use of Clean-Check valves.
