HANTEMP Controls is now offering the model S4At Stainless Steel Solenoid Valve. While ideal for ammonia, these solenoid valves can 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. Functionally and dimensionally, the S4At replaces similar models from traditional steel & iron valve manufacturers.
