FCT Dual Plate Wafer Check Valve

FCT Dual Plate Wafer Check Valve – Reliable, Lightweight Non-Slam Protection

FCT dual plate wafer check valves use a center-hinged twin disc that opens with forward flow and closes immediately upon reversal. The spring-assisted mechanism ensures non-slam closure to protect equipment from surge and water hammer. Their wafer-style body fits snugly between flanges, minimizing footprint and installation time.

Designed for horizontal or vertical installations, they are widely used in cooling systems, water treatment, pump discharge lines, and compressed gas systems.
