Aladco Equa-Check Valve

The Aladco Equa-Check valve is a normally closed check valve that can be either overridden manually or by air piloting to allow two-way flow.  The tightly sealed Equa-Check valves are used on pneumatic devices to stop motion upon loss of air pressure and prevent the device from drifting. The Equa-Check valve is specifically designed for use in pneumatic applications where two-way flow is maintained to a device for load balancing. Combined with a pressure regulator to control air flow to and from a pneumatic tool balancer or manipulator, the Equa-Check valve will hold position and not be allowed to drop until the override of the Equa-Check valve is activated.
