1PC Wafer Disc Check Valve PN16/PN40
The 1PC Wafer Disc Check Valve PN16/PN40 is designed to prevent backflow in industrial pipeline systems. The valve adopts a compact wafer-type structure with a disc check mechanism, allowing fluid to flow in one direction while automatically closing when reverse flow occurs.
Manufactured with a precision investment casting body and cap, this wafer check valve provides excellent structural strength, corrosion resistance, and long service life in demanding industrial environments.
The wafer design allows the valve to be installed between pipeline flanges, saving installation space and reducing system weight. This compact design makes it ideal for applications where space efficiency and reliable backflow prevention are essential.
Designed and manufactured according to ASME B16.34, this valve meets international industrial standards for pressure and structural performance.
Supplied by SHAANXI GOLD-STONE I/E CO., LTD., the wafer disc check valve is widely used in oil and gas pipelines, water treatment facilities, chemical processing systems, and general industrial fluid control systems.
