What is a wafer dual plate check valve?
The dual plate check valve is a general purpose check valve that is stronger, lighter in weight and smaller in size than traditional swing check valves.
The dual plate check valve utilizes two spring-loaded plates attached to a central dumpling chain pin. When the flow is reduced, the plates are closed by the action of the torsion spring, and there is no need for reverse flow.
This design provides the dual advantages of no water hammer and no impact at the same time.
Consisting of 2 discs attached to the valve body by a pin and operated by the action of springs, which immediately start closing the valve, when the fluid stops, dual plate check valves are used to prevent back flow and also work as a prevention for water hammer.
Dual Plate Check Valves are made from a wide range materials including cast iron, special stainless steels, ect. They can be soft seat or metal seat construction and also have the ability to adjust the spring torque according to the application, which makes it a product suitable for general and special purposes.

Advantages of wafer dual plate check valve:
#1 Lightweight, so easier to handle and self-supporting. More compact and well-structured design.
#2 The same valve can be installed horizontally or vertically.
#3 Due to the spring assisted closing, only the double plate check valve can be installed upside down.
#4 Reduced pressure drop and energy loss regardless of pressure rating.
#5 Efficient and reliable sealing under most flow and pressure conditions.
#6 The valve closes before the flow reverses and the velocity is zero.
#7 Water hammer is almost non-existent.
#8 Long service life and trouble-free operation.
#9 Small in size, light in weight, compact in structure,easy in maintenance.
#10 Two torsion springs are used excreting on each of the pair valve plates,which close the plates quickly and automatically.
#11 The quick-close action prevents the medium from flowing back and eliminates water hammer effect.
#12 Short body structure length and good rigidity.
#13 This valve is tightly sealed, without leakage under the pressure water test.
#14 Safe and reliable in operation,high interference-resistance.
