Product Description

About Wafer Type Dual Plate Check Valves

Zhongguan specializes in producing dual plate (double disc) check valves with clamps. The structural design of the valve utilizes two spring loaded plates connected to the center dumpling chain pin. When the flow rate decreases, the plate closes under the action of the torsion spring and does not require reverse flow. This design provides a dual advantage of no water hammer and no impact. A double plate check valve consists of two valve discs, which are connected to the valve body through a pin and operated by the action of a spring. When the fluid stops, the spring immediately begins to close the valve. The double plate check valve is used to prevent backflow and also to prevent water hammer.

Design Features & Installation: 

- Smaller and lighterin design than conventional check valves and the installation and pipework layoutexpenditure is considerably reduced.

- Can be installed horizontally, with the pins in a verticalposition or vertically with flow in the upwards directionIt is recommended that valves are installed a minimumof ten pipe diameters down stream from a source ofturbulence ie. a pump or elbow.

- The overall length of the body has been reduced to theextent that in the fully open position, the discs extendsinto the downstream pipeline.Therefore allow at leastone pipe diameter downstream before installing valves, pipe bends or tees etc.

- Flow direction indication on the outside of the body
