10 sanhuaeurope.com SANHUA GENERALPRODUCTCATALOGUE O series electronic expansion valve are mainly used in air conditioning systems variable refrigerant flow to realize automatic adjustment of refrigerant flow rate and make the air conditioning systemwork under the best working condition for thepurposeof fast cooling, precise temperature control and power saving. These valves can also be used for other controls. These valves are reversible which can automatically control the flow of refrigerant in either heating or cooling mode. O SERIES ELECTRONIC EXPANSION VALVE FEATURES • HIGHPRECISION: FULL OPENPULSE 2000 • LONG LIFE • LOWNOISE • ENERGY SAVING GENERAL SPECIFICATIONS • Applicable for all common HCFC, HFC, HC, HFO refrigerants 1) such as: R22, R134a, R404A, R407C, R410A, R507, R407A/F, R290, R1234ze, R1234yf, R32, R448A/R449A, R452A, R450A/R513A • Capacity: 1USRT~13.3USRT (R22 Nominal Capacity) • Applicable medium temperature: -30ºC ~ +70ºC (electrified rate below 50%) • Applicable ambient temperature: -30ºC ~ +60ºC (electrified rate below 50%) • Relative humidity: below 95%RH • Installation mode: Coil upwards, central axis of valve rotor within ±15°vertical to horizontal surface ELECTRICAL PARAMETERS • Rated voltage: DC12V (±10%), rectangular wave; • Actuating mode: 4-phase 4-step permanent magnet stepping motor of speed reduction type; • Excitation mode: 2-2 phase excitation, monopole actuation; • Excitation rate: 100PPS~250PPS (opening excita- tion speed ≤ closing excitation speed, the ending excitation mode maintains more than 0.1S); • Current of coil:80mA/phase(20ºC) • Resistance of coil:150±15Ω/phase(20ºC) • Insulation grade of coil: E Note: 1) Cooling capacity besides R22 pls contact SANHUA local sales representative
