Dual Plate Check Valves Supplier
The Dual Check Plate Valve is an all-purpose non return valve that is much stronger, lighter and smaller in size compared to a conventional swing check valve.
Kaizen Steels is a leading Manufacturer, Supplier Dual Plate Check Valve designed to address the issues commonly found in swing and lift check valves. It features two spring-loaded plates attached to a central hinge pin. As the flow slows down, these plates close automatically through torsion spring action, eliminating the need for reverse flow.
This innovative design provides the dual benefits of preventing water hammer and ensuring a non-slam operation. These qualities make the Dual Plate Check Valve, also known as the Silent Check Valve or Wafer Check Valve, one of the most efficient and reliable options in flow control.

Technical Performance
- Compact Design: Features a short face-to-face connection that enhances hydraulic efficiency.
- Low Pressure Drop: Ensures minimal loss of pressure across the valve.
- Compact Size: Designed to save space without compromising functionality.
- Vulcanized Seal: The seal is integrated into the seat of the body for effective sealing.
- Spring-Assisted Closing: Springs aid in closing the plates, reducing the risk of water hammer.
- Equilibrated Forces: Dual springs balanced forces on the plates for smooth operation.
- Reduced Friction: Stops on the plates minimize friction between the plates’ ears and the shaft.
- Symmetrical Flow: Centering pin ensures symmetrical flow when the plates are fully open.
- Versatile Installation: Can be installed horizontally or vertically in pipelines.
- Lifting Rings: Available from DN 250 for easier handling.
