Nozzel check valves are also called as Non Slam Check Valve, which is used as protection against reverse flow whenpower failure in areas where noise pollutionor water hammering is a critical issue. lt canprovide not only quiet performance but also low head loss

Technical Data.
Size Range: DN50-600mm

Pressure Ratings:1.0Mpa; 1.6Mpa; 2.5Mpa

Features:

·?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.

·?One of the lowest head loss check?valve, big save in pumping power?cost, valve disc with shorter stroker and spring reverse faster than most?of check valve.?

·?Coated with powder epoxy both inside?& outside for corrosion resistance.

·?Bronze bushing reduce wearing?problem during operation.?

·?Hydrodynamic design with spring?ensures non slamming and water?hammerless.?

·?Stainless steel spring hidden in the?diffuser under protection while valve?in operation.?

·?Disc will positively close before?reverse flow, and maximize the?closing speed up to 0.2 Sec.?

·?Installation can be vertical/horizontal/?inclined.?

·?Comply with EN 558-1, ISO 5752?and EN 1092-2, ISO 7005-2 flange?dimension.

Application:
Mainly used for clean water, precleaned, sewage water, Fire-fighting, Irrigation,
