FEATURE
- Elastic body seat that contacts the plate is formed with body and ensures the perfect sealing even after the prolonged use.
- Simple design and heavy duty stainless steel screening is easy to maintain.
- Body and plate is light weight, and designed to prevent the additional loading when operating the pump.
- The internal epoxy coating on the in/out side of the valve is possible.

ADVANTAGE
- Face-to-face dimensions for Dual Plate Wafer Check Valves are about one fourth of a Swing Check Valve.
- Weight is as little as about 20%of the corresponding Swing Check Valve due to the compact design.
- Dual Plate Wafer Check Valves have a spring design to close valves more efficiently when the backfl occurs to reduce the water hammer.
- These valves have the lower pressure drop than Swing Check Valves because of little friction resistance.
- Dual Plate Wafer Check Valves are less expensive than Swing Check Valves because of the lightness and compact design.
- Because Dual Plate Wafer Check Valves are flangeless, they are installed between flanges.
- Normal installation method for horizontal flow is with the hinge pin in vertical position.
- Installation is available for both horizontal and vertical piping.
