Thermal Conditioning Expansion valve regulate the injection of refrigerant liquid into evaporators. Injection is controlled by the evaporators superheat. CTV,DTV series Thermal conditioningExpansion valve can be used for refrigeration cabinet, ice machine, dehumidify unit, and refrigeration and air conditioning requirements in a wide range of temperature. Characteristics 1. Constant superheat adjusting performance. 2. Interchangeable orifice assembly. 3. Wide range of evaporating temperature: -40→+10 .C. 4. Can be supplied with MOP (Max. Operating Pressure). 5..Adjust to refrigeration R410a Type anddata Model EqualizationEqualization connection (in.)Connection formConnection Inlet×Outlet (in.)Capillary tube (m)CTVInternalFlare SAE3/8×1/21CTVEExternal1/4 SAEDTVInternalSolder ODFDTVEExternal1/4 ODFModelOrificenumberNominal capacity(KW)R134aR22R407CR404A/R507R410ACTV(E)-DTV(E)-00.651.141.130.81.3211.52.82.81.853.2522.54.74.573.15.45347.57.0358.746.712.211.968.114.1558.214.914.49.917.2869.517.216.911.419.95Nominal capacities base on +38°C condensing temperature,+4°C evaporating temperature and 1K liquid sub cooling at the inlet of the expansion valve.
