Anti Water Hammer Non Slam Check Valve Made Of High Grade Ductile Iron

Anti Water Hammer Non Slam Check Valve Made Of High Grade Ductile Iron

 

Description:

 

Non Slam Check Valve is usually installed as a protection device against reverse flow when power failure in areas where noise pollution or water hammering is a critical issue. It can provide quiet performance and low head loss. The faster closing speed can decrease the reverse speed of water to minimize the water hammer.

 

 

Features:

 

·Very short stroke, quick close

·Diffuser design- lowest head loss and streamline flow

·Zero leakage of rubber disc seat

·Spring hidden on back side of disc prevent clogging

·Bronze bearing-long life service

·Disc will positively close before reverse flow, and maximize the closing speed up to 0.2 Sec.
· Installation can be vertical/horizontal/inclined.

·High strength ductile iron body used for durability and less weight.
·Advanced dynamic design of single body with diffuser provides streamline flow and assures lower head loss.
·Stainless steel spring hidden in the diffuser under protection while valve is working.
·Comply with EN 558-1, ISO 5752 and EN 1092-2, ISO 7005-2 flange dimension.
