FCT Non Slam Check Valve

FCT Non Slam Check Valve

FCT Non-Slam Check Valve – Fast Closure Without Hammer or Noise

FCT non-slam check valves use a spring-assisted disc mechanism to close the valve immediately upon flow reversal, eliminating the slamming effect and water hammer typically seen in swing check valves. Their axial or inline design ensures low pressure drop and smooth operation across a range of fluids.

These valves are suitable for critical flow systems such as boiler feedwater lines, condensate return, cooling systems, and compressor discharge piping where quiet and reliable operation is required.
