Wafer Type Check Valve

A wafer type check valve is an ultra-compact, inline non-return valve designed to slide between a pair of standard pipe flanges to prevent fluid backflow in space-constrained piping networks. Unlike bulky flanged check valves, the wafer design features a slim, face-to-face profile that eliminates traditional body flanges, allowing it to be securely clamped into position using a single set of long stud bolts that span the entire width of the valve. Driven entirely by fluid kinetics, the valve utilizes a thin internal swing disc, single-plate, or dual-plate mechanism that automatically lifts or splits open when upstream pressure exceeds downstream pressure, and slams shut under backpressure or spring assistance when flow decelerates. Piping layout contractors and mechanical project managers can minimize installation footprints and eliminate water hammer risks by importing certified wafer type check valves directly from leading manufacturers in China via our advanced B2B commercial platform.
