    Wafer check valve is a type of check valve that is used to regulate and control the flow of fluids through pipelines while preventing backflow. High quality wafer check valve is typically used in applications where space is limited, such as in HVAC systems, water treatment plants, and industrial processes.

    Wafer check valve application

    Tips: How does a stainless steel wafer check valve prevent backflow in a piping system?

    A stainless steel wafer check valve prevents backflow in a piping system by using a disc or flap that is mounted on a hinge or held in place by a spring. The disc or flap is positioned in such a way that it can swing or lift in one direction, allowing fluid to flow through the valve, but is held closed when fluid tries to flow in the opposite direction.

    When the fluid in the piping system is flowing in the forward direction, the pressure of the fluid pushes the disc or flap open, allowing the fluid to pass through the valve with minimal resistance. However, when the fluid flow reverses or slows down, the pressure of the fluid decreases, and the disc or flap swings back into place, closing the valve and preventing backflow of the fluid.

    The spring or hinge mechanism that holds the disc or flap in place can be adjusted to ensure that the valve opens and closes at the appropriate pressure levels. Additionally, the materials used to make the valve, including the stainless steel body and the disc or flap, are highly durable and resistant to corrosion, ensuring that the valve can perform reliably over a long period of time.

    Works well
    I recently installed this 2 inch wafer check valve in the plumbing system at home and it has been working flawlessly. The valve is easy to install and provides efficient flow control.
