Product Description
The Spring Loaded Disc Check Valve (Wafer Type Non-Return Valve) is designed
to provide reliable protection against reverse flow in industrial piping systems. Featuring a
compact wafer-type construction with a spring-assisted disc, the valve closes immediately when
the flow stops, preventing backflow and reducing water hammer. Its lightweight, flangeless
design allows easy installation between standard flanges in both horizontal and vertical
pipelines. Available with metal or soft seats, this valve is suitable for handling liquids,
air, gas, steam, and a wide range of industrial process media.
