Description

Available Models: SD-NRV200FF-D / SD-NRV300FF-D

Check valve or Non Return Valve allow fluid to flow in one direction only. Large fire protection systems sometimes experience severe water hammer caused by backflow when the automatic control shuts down the fire pump. Where conditions can be expected to cause objectionable water hammer, a listed anti water-hammer check valve should be installed in the discharge line of the fire pump. According to NFPA20, 4.15.6* – A listed check valve or backflow preventer shall be installed in the pump discharge assembly.

S.A Enterprise & Engineering Solution provides you UL certified check valves manufactured by world class brand – SHIELD.
