Thin Type Single Disc Wafer Swing Check Valve
Product Details
A Single Plate Check Valve is a compact, wafer-type non-return valve designed to prevent reverse flow in piping systems. It features a single swing disc that opens automatically under forward flow and closes quickly when the flow stops or reverses, ensuring reliable backflow prevention and system protection.
Working Principle
When the fluid flows in the correct direction, the pressure pushes the disc open, allowing smooth passage through the valve. Once the flow stops or reverses, the disc automatically swings back to the seat, closing the valve and preventing reverse flow without the need for external control.
