Collection: Praher K4 Wafer Swing Check Valves

Swing check valves are commonly used in piping systems to allow fluid to flow in one direction while preventing backflow in the opposite direction. The swinging disc inside the valve is typically held in place by a hinge mechanism. When the flow of fluid is in the desired direction, the disc swings open, allowing the fluid to pass through. However, if there is any reversal in flow, the disc swings back and closes, preventing the fluid from flowing back.

These valves are available in various sizes and materials to accommodate different types of fluids, pressure ratings, and temperature ranges. They are widely used in industries such as oil and gas, water treatment, chemical processing, and HVAC systems.
