Wafer Check Valves
Wafer style Silent Check Valves
have the same operating principle as the Globe Check valve, but they are offered in a configuration that allows placement between two flanges. are designed to close before the pump stops
completely. This prevents flow reversal, which eliminates water hammer and the surges associated with check valve closure. Fully automatic, spring-loaded and double-guided, the valve opens
as the pump starts, and closes just prior to flow reversal upon pump outage. With a standard cast
iron body, bronze seat, disc and bushing, and a stainless steel spring, all internal parts of the Wafer Style Check Valve are field replaceable for ease of maintenance. Resilient seats are
highly recommended
for potable water or drip tight applications.
