HS4A Solenoid Valves

These advanced design, strong bodied, precision manufactured solenoid valves control the on-off flow of refrigerant. They are superior in their ability to overcome dirt and sticky oil during opening and closing, and operate smoothly even in an oil-free “dry” system. When electrically energized, the upstream pressure is ported through the pilot solenoid to the top of the piston to push it downward and open the main valve seat wide; when de-energized, pressure is no longer ported to the top of the piston and a spring closes the main valve seat to stop flow in the arrow direction on the valve body.

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.)
