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 an internally plumbed air pilot or a single override button that releases both sides at once.

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.  Fully sealed for use in clean/sanitary environments.

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 to create an internal pressure balance between the IN pressure and the PILOT pressure, making it ideal for balancing and tensioning applications.

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.
