PVC VALVE
PVC Wafer Check Valve
PVC wafer check valve is a slim, lightweight dual-plate (dual-disc) check valve designed to fit between pipe flanges. Spring-assisted discs open under forward flow and close instantly when flow stops, minimizing water hammer. Its wafer body design reduces installation space and weight compared to full-body check valves. Suitable for water treatment, industrial, and chemical systems.
