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.
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 sanitary or harsh/dirty environments.
Equa-Check®
4-Series, Single Check
The Equa-Check® valve, designed specifically for pneumatics, is a patented Aladco® product. Pilot pressure is balanced by the IN chamber pressure. Primarily used for applications where two-way flow is desired by maintaining pilot pressure higher than inlet pressure.
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.
