What is A DUAL PLATE CHECK VALVE Used For?

A dual plate check valve, also known as a dual-disc check valve, is a type of valve used to prevent backflow in piping systems. It consists of two hinged plates (discs) that open and close to allow or block the flow of fluid.

How It Works?

  • Structure: The valve body houses two plates that pivot on a common axis. These plates are generally designed to move in a swinging motion.
  • Operation: When fluid flows in the forward direction, the plates open to allow the fluid to pass through. When the flow reverses or stops, the plates close against the valve seat to prevent backflow.

Applications

They are commonly used in various industrial applications, including water treatment plants, power generation, and HVAC systems, where reliable prevention of backflow is crucial.

Advantages

  • Compact Design: Dual plate check valves are typically more compact and lightweight compared to other check valve designs, like swing check valves.
  • Low Pressure Drop: They offer lower pressure drop because of their streamlined design, which is beneficial for maintaining efficient flow in a system.
  • Quick Response: The dual plates close quickly in response to backflow, reducing the risk of water hammer and system damage.
