FCT Pressure Seal Tilting Disc Check Valve

FCT Pressure Seal Tilting Disc Check Valve – Non-Slam Performance in Critical Systems

FCT pressure seal tilting disc check valves are designed to meet the demands of high-pressure steam, thermal oil, and critical process flows. The tilting disc rotates slightly off-axis for quick closure, eliminating slam and reducing seat wear, while allowing for smooth forward flow with minimal turbulence.

The pressure seal bonnet compresses tighter as pressure increases, eliminating the need for heavy bolting and reducing valve body weight—ideal for boilers, power plants, and high-temperature lines where space and sealing performance are equally important.
