Nozzle Check Valve with anti water hammer and low Head Loss function
NSCV- Non Slam Check Valve is generally used as protection against reverse flow when power failure in areas where noise pollution or water hammering is a critical issue. It has two outstanding features: anti water hammer and low head Loss function. The faster closing function can decrease the reverse speed of water to minimize the water hammer.
· Extremely short stroke can help quick closely
· Diffuser design- lowest head loss and streamline flow
· 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.
· 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 in operation.
· Comply with EN 558-1, ISO 5752 and EN 1092-2, ISO 7005-2 flange dimension.
· No leakage of rubber disc seat.
· Installation can be vertical/horizontal/inclined operated.
