Nu-Check® 3-Series, Single Check
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.
Dual-Check® 6-Series, Double Check
The Dual-Check® valve, designed specifically for pneumatics, is a patented Aladco® product. It is the only parallel check valve that can be manually overridden with a single override button or with an internally plumbed air pilot. The Dual-Check® is sealed and can be used in either sanitary or harsh/dirty environments.
Clean-Check® 5-Series, Single Check
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.
Equa-Check® 4-Series, Single Check
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.
