The gravity closing feature makes these valves ideal for systems that use a VFD or compressor unloading feature to reduce capacity as they can tolerate load fluctuations better than alternative check valve technologies. All CK1 check valves are flanged and have a manual opening stem for manual operation. The 20-32 mm (3/4 - 1-1/4”) port size valves have a PTFE seat; larger valves have a metal to metal seat. A minimum pressure difference of .03 bar (0.5 psi) is required to open the valve.
