FCT Axial Flow Check Valve ( Nozzle Check Valve)

FCT Axial Flow Check Valve ( Nozzle Check Valve)

FCT Axial Flow (Nozzle) Check Valve – Silent Reverse Flow Protection with Minimal Pressure Loss

FCT axial flow check valves, commonly referred to as nozzle check valves, are engineered to provide non-slam, fast-closing action in systems with high velocity and rapid flow reversal. The spring-assisted disc moves axially within the flow path and returns to the seat instantly when flow stops or reverses—eliminating water hammer and mechanical shock.

With their streamlined flow path and compact body, these valves are ideal for vertical or horizontal mounting and are frequently used in compressor discharge lines, cooling water systems, and turbine or boiler feed applications.
