A wafer check valve is a compact non‑return valve designed to prevent backflow, using a swing disc or dual plates housed in a thin “wafer‑style” body that fits between flanges. When flow moves in the forward direction, the disc opens fully to minimize pressure loss; when flow reverses, the disc quickly closes to protect pumps, pipelines, and equipment. [likvchina]
Compared with traditional swing check valves, wafer designs require less face‑to‑face length and weight, which is ideal for tight pump rooms and retrofit projects in water and wastewater plants. Dual‑plate wafer check valves further reduce slamming and water hammer by using torsion springs and a split‑disc construction. [klinger]
