Sporlan Thermostatic Expansion Valves

The thermostatic expansion valve (TEV) controls the flow of liquid refrigerant entering the direct expansion (DX) evapo­rator by maintaining a constant superheat of the refrigerant vapor at the outlet of the evaporator. Superheat is the differ­ence between the refrigerant vapor temperature and its sat­uration temperature. To measure the superheat, the TEV controls the difference between the actual temperature at the sensing bulb and the saturation temperature corresponding to the suction pressure at the sensing bulb location. By controlling superheat, the TEV keeps nearly the entire evaporator surface active while not permit­ting liquid refrigerant to return to the compressor.  The ability of the TEV to match refrigerant flow to the rate at which refrigerant can be vaporized in the evaporator makes theTEV the ideal expansion device for most air conditioning and refrigeration applications.

All Sporlan TX Valves can be easiealy rebuilt for increased life span and more precise control. They are available for both ammonia and freon applications from 1 to 100 Tonnes.
