Wafer Check Valve – Dual Plate, Stainless Steel / Ductile Iron, Spring Return

The Wafer-type check valve is a thin-type check valve that is clamped between the pipe flanges using bolts. It is specially designed for space-constrained pipeline systems. Compared to traditional flange check valves, it has a more compact structure and is lighter in weight. It is suitable for single-direction flow control requirements in industries such as petroleum, chemical engineering, and water treatment.
