The Cla-Val Model 100-03 Powercheck Valve is a hydraulically operated diaphragm valve with a built-in check feature to prevent return flow. When a pressure reversal occurs, the valve will immediately close, preventing reverse flow through the valve. The split stem will allow the disc retainer assembly to check closed regardless of the position of the diaphragm.
