High Pressure Solenoid Module

This advanced design valve is ideal as a standard, stock, ammonia liquid line solenoid valve. While primarily for ammonia, this valve is also suitable for R22, R134a, CO2 and other approved refrigerants.

Most common use is to automatically stop liquid line feed to recirculating liquid overfeed evaporators, to float switch controlled accumulators, and to thermal expansion valves; it is also suitable for hot gas defrost, and evaporator suction. (Note: for gravity liquid drain or equalization applications use low pressure drop HCK2 gas-powered suction stop valve or HS9B gas-powered solenoid valve.) 

Effective in 2025, the HS7 product line will include Hansen’s new robust solenoid operator that features a rugged stainless steel housing and is sealed to the body with a reliable aluminum gasket.
