Dual Plate Wafer Check Valve
A dual plate wafer check valve is a type of check valve that consists of two plates that are hinged together. It is designed to allow fluid flow in one direction while preventing flow in the opposite direction. The two plates are connected by a hinge pin, and a spring is used to keep the plates closed when there is no flow in the desired direction. When fluid flows in the desired direction, the pressure of the fluid pushes the plates open, allowing the fluid to pass through. When the flow stops or reverses, the spring closes the plates, preventing backflow. Dual plate wafer check valves are commonly used in a variety of industrial and commercial applications, including water treatment, oil and gas systems.
- Hinge pin
- Handle or Lever
- Dual plate wafer check valves have a compact design that allows them to be installed in tight spaces.
- These valves are relatively inexpensive compared to other types of check valves.
- Dual plate wafer check valves have a low pressure drop across the valve, which helps to reduce energy costs and prolong the life of pumps and other equipment.
- Dual plate wafer check valves are relatively easy to maintain, as they can be easily disassembled and reassembled for cleaning or replacement of parts.
- They valves can be used for both horizontal and vertical flow and can handle bidirectional flow.
- Dual plate wafer check valves are lightweight, which makes them easy to install and handle.
- They are relatively quiet during operation, which makes them suitable for use in noise-sensitive applications.
- They require low torque to operate, which reduces the size and cost of actuators and other control devices.
Industries which use them
- Oil and Gas Industry
- Water and Waste water Treatment Plants
- Power Generation Plants
- Chemical and Petrochemical
- Pharmaceutical Industry
- Food and Beverage Industry
- Marine Industry
- Dual plate wafer check valves are used in pipelines to control the flow of fluids, gases, and other materials, and to prevent backflow.
- Dual plate wafer check valves are used to protect pumps from backflow, which can damage the pump and reduce its efficiency.
- These valves are used in compressed air systems to control the flow of air and prevent backflow, which can damage the compressors and reduce their efficiency.
- They are used in process control applications to control the flow of fluids and gases in industrial processes.
- Are used in fire protection systems to control the flow of water and other extinguishing agents, and to prevent backflow.
