Check Valves

Check Valves are suited for vacuum operations.

Vacuum check valves work with venturi vacuum pumps and switches to seal and maintain vacuum levels. With cracking pressure rated at less than 1 in. Hg., they allow air flow in one direction only. Valves can be manually operated or automatically controlled by vacuum switch. Able to be used in any orientation, valves come in 1/4 and 3/8 in. NPT sizes and are made of chrome plated brass with...
