Features of Hydraulic Non-Slam Check Valve

1. 2. Automatic control using medium energy;3. Prevent water hammer phenomenon;4. Slowly-closing silencing.Principle of Hydraulic Non-Slam Check Valve

When the pipe supplies water from the inlet end of the valve, the water from the needle valveand one-way valve enters the valvecover control room and then is discharged downstream through the ball valve. Due to the small opening of the needle valve, the discharge speed of the control room is greater than that of the inlet to replenish water, thus reducing the pressure in the control room. The inlet pressure acting under the main valve disc all the time lifts the main valve disc, thereby opening the main valve disc and supplying water downstream. When the pipeline stops supplying water, the downstream water begins to flow back. Due to the effect of the one-way valve, the backflow water cannot flow out after entering the valve cover control room through the ball valve. As a result, the pressure of the valve cover control room increases gradually and the main valve disc is closed tightly.

Installation and Commissioning of Hydraulic Non-Slam Check Valve

Needle valve and ball valve adjust together to get the best opening or closing speed. For specific use, please consult ZECO Valve Group.
