Nozzle Type Non Slam Check Valve

Nozzle Non Slam Check Valve

Nozzle Non Slam Check Valve refers to the automatic opening and closing valve disc that rely on the flow of the medium itself, which is used to lower the noise when open or close.

 The nozzle non-slam check valve is categorized as an automatic valve with primary functions including preventing the reverse flow of the fluid, averting the reversal of the pump and drive motor, and discharging the contents of the container. Additionally, it serves the purpose of supplying lines for replenishing auxiliary systems where the pressure may exceed the system pressure.

Features of Nozzle Check Valves

Nozzle check valves are one of the best check valve designs due to the following features:

-Fast respond to the flow changes: Disai Non Slam Check valves deliver an effective dynamic response under various flow deceleration conditions, this unique design features result in superior performance, fast response and lower pressure loss in piping systems.

-Very short closing stoke.

-Low weight moving parts minimizing wear.

-Non-slam closure.

-Low head loss: An optimised flow cross-sectional area as well as a valve disc and valve stem gasket designed for minimum flow resistance ensure minimum head losses with the non slam nozzle check valve. 

Main Components Of Nozzle Type Non Slam Check Valve

Nozzle Type Non Slam Check Valve is mainly composed of body, seat, guide body, valve disc, bearing and spring and other main parts, the internal flow path adopts streamlined design with minimal pressure loss. The valve flap opening and closing stroke is very short. It can be closed quickly to prevent huge water hammer sound when the pump is stopped. It has the characteristics of silent closing. Mainly used for water supply and drainage, fire, HVAC system, can be installed in the pump outlet to prevent backflow and water hammer damage to the pump.
