    Tips: What is a wafer check valve?

    A wafer check valve is a type of check valve that is used to prevent the reverse flow of fluids in pipelines. It is called a "wafer" check valve because it is designed to fit between two pipe flanges, making it compact and easy to install.

    The wafer check valve operates by allowing fluid to flow in one direction while preventing flow in the opposite direction. It consists of a disc that moves up and down in response to the fluid flow. When the fluid flows in the desired direction, the disc moves up and allows the fluid to pass through. When the fluid tries to flow in the reverse direction, the disc is pushed down by the fluid pressure and seals against the valve body, preventing backflow.

    Wafer check valves are typically made of materials such as cast iron, stainless steel, or PVC. They are used in a variety of applications, including HVAC systems, water and wastewater treatment, oil and gas pipelines, chemical processing plants, and the food and beverage industry.

    Overall, the compact design and reliable operation of wafer check valves make them a popular choice for preventing backflow in pipelines and ensuring that fluids flow in the desired direction.
