1/4" x 1/2" SAE HF Series Thermal Expansion Valve (0.5 Ton)

Emerson's Thermal Expansion Valves are designed for a wide range of air conditioning, refrigeration, heat pump, and chiller applications.

Emerson uses stainless steel power elements that are not susceptible to corrosion. Emerson offers products with conventional, as well as balanced ported designs that are advantageous when applied to systems with large load variations and/or floating head applications. Emerson also manufactures bi-flow designs for use in heat pumps and many of our Thermal Expansion Valves have a take-apart design for ease of service. Emerson thermal expansion valves cover a wide range of nominal capacity from ½ ton to 100 tons.
