Solenoid valve (HS)

The Hansen HS solenoid valves are designed for industrial refrigeration systems operating with NH₃. The minimum required opening pressure is very low, and the PTFE seal ensures perfect sealing. Coils are available in 24 V AC, 24 V DC, 110 V AC, or 230 V AC and are supplied as standard with a DIN plug connection.

The solenoid valves are supplied as standard with weld flanges. To minimize installation time, Hansen valves can be directly connected to Hansen filters (ST) and check valves (HCK). In most cases, Hansen solenoid valves can replace R/S and Parker valves without modifications. All Hansen control valves are CE-PED compliant.
