1.Details

DI. Body Silent Check Valve, disc/brushing bronze B62, Bronze Disc,Bronze

Stem,EPDM Seat, S304 Spring,Flanged to PN16, Working Pressure:PN16,

Blue Ral5015 FBE Coated.

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.
