The Equa-Check™ Valve, designed specifically for pneumatics, is a patented ALADCO® product. It is the only check valve on the market with both manual and pilot release capabilities. Equa-Check™ Valves are air pilot operated check valves with equal internal balancing between the IN pressure and the PILOT pressure. The internal pressure balancing in the valve enables it to perform some unique controlling functions in pneumatic applications. Load balancing systems are a type of application that can benefit from the functions of an Equa-Check™ Valve.

The Equa-Check™ Valve has not been designed for use on vacuum, air over oil or hight pressure applications.
