These reliable, flanged bodied valves are ideal for use as standard, stock refrigerant solenoid valves. While primarily for ammonia, these valves are also suitable for R22, R134a, CO2 and other approved refrigerants and warm refrigeration oil. Most common use is to automatically stop liquid feed to recirculating liquid overfeed evaporators, and as liquid makeup solenoid valve for pump recirculators. They are also suitable for hot gas defrost supply and evaporator suction stop applications. (Note: For gravity liquid drain or equalization applications, use low pressure drop Hansen Type HCK2 gas-powered suction stop valves or Type HS9B gas-powered solenoid valves.)
