SILENT CHECK VALVE offer all the features as the standard check valve,with
the addition of a spring-loaded hinged flapper mechanism
which forces the
flapper to fully colse against fluid flow as the pump shuts down.This rapid
closing action against pressure before any flow reversal can occur,eliminates
noise caused by hydraulic shock(water hammer).
Check valve(also known as non-return valves) allow fluid to flow in one
direction only.In additon,these valves open automatically when there's pressure
coming from the inletside,however,the valve is pushed closed if there is
pressure from the outlet side-preventing back-flow which is greater than the outlet side.
