Check Valve - Spring Close

Hansen In-Line HCK4

These flanged valves (sizes 16 to 100ND) prevent reversal of flow of refrigerant in discharge, hot gas, liquid and suction lines. Not suitable for where constant pulsing pressure applications occur, refer Hansen HCK1 type which is more suitable pulsing pressure.

These compact in line check valves offer reliable operation regardless of mounting position. The spring closing disc type non return valve uses stainless steel disc and springs with a plated body to suit Hansen flanges, or close coupling to Hansen valves with use of a male adapter ring.

Requires less than 14.5kPa pressure drop for wide open operation, suitable for Ammonia, CO₂ and other common refrigerants approved by Hansen.
