Expansion Valves

Expansion Valves

TEA Thermostatic Expansion Valve, for Ammonia

Thermostatic expansion valves regulate the injection of refrigerant liquid into evaporators. Injection is controlled by the refrigerant superheat. The range of thermostatic expansion valves cover different valves designed for specific applications. The valves are delivered with connections in flare, solder copper or stainless steel / copper bi-metal connections.Temperature range from –60°C to 50°C.Rated capacity: 0.5 to 1890 kW (R 22).

TEAT, Complete Valves

TEAT desuperheating valves are used to inject refrigerant into the suction line of the refrigeration system to reduce the high discharge temperatures that can occur when the system operates with highly superheated suction vapour. TEAT valves are also used in two-stage refrigeration plants to control liquid injection into the intercooler and for temperature regulation of the medium, e.g. the temperature of the oil in a screw compressor.Refrigerants: HCFC, Non-flammable HFC refrigerants, and R717 (Ammonia).
