Hantemp Controls, a manufacturer of stainless steel controlled ball valves, float switches, pressure regulators and flange unions for industrial refrigeration systems, is now offering the model S4At Stainless Steel Solenoid Valve.
While ideal for ammonia, these solenoid valves are designed to also control CO2, fluorinated refrigerants, glycols, pure water, light oils and other approved liquids.
For ammonia refrigeration systems, they can be used for overfeed/recirculating liquid lines, suction lines over 10°F, hot gas lines, high pressure liquid lines and discharge gas lines.
