Product Description

 Ductile Iron Cast Iron Silent Check Valve
The function of Check Valve is to allow the medium to flow in one direction only and prevent the flow in the opposite direction. Usually, the valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the fluid pressure and the dead weight of the valve disc act on the valve seat, thus cutting off the flow.
Check valve can be divided into Swing Check Valve (rotating according to the center of gravity) and Lift Check Valve (moving along the axis).
According to the structure, it can be divided into Lift check valve, Swing check valve and Butterfly check valve
1. Lift check valve is divided into vertical type and horizontal type
2. Swing check valve is divided into three types: single type, double type and multi type.
3. Butterfly check valve is straight through type.
The above check valves can be divided into threaded connection, flange connection, welding connection and clamp connection.

Product Name:  Silent (Quiet) Check Valve


Structure and Application: 
This kind of valve is suitable for water supply, drainage, fire control and HVAC system. It can be installed at the outlet of water pump to prevent medium backflow and water hammer from damaging the pump.
Streamline design is adopted for internal circulation, with minimal pressure loss, short opening and closing stroke of valve disc, which can be quickly closed when the pump is stopped, so as to prevent huge water hammer sound and form a silent effect.
