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®
