Description:Applications: electronic expansion valve is used for home air conditioners, mainly installed in the converter air conditioning system, to regulate the refrigerant flow automatically. Hence, the air conditioning system will keep working with the best capacity, quick cooling, accurate temperature controlling and power saving. The electric expansion valve can also be used for other kind of flow controlling due to automatic controlling performance of the refrigerant flow under cooling and heating conditions Specifications: 1) Air flow: 310NL/min (2.5MPa), 480NL/min (above 3.5MPa) 2) Capacity: 1.5USRT / 5.3kW 3) Flow feature: B Technical parameters: 1) Ambient temperature: -30 - +60oC 2) Flow temperature: -30 - +90oC 3) Ambient humidity: below 95% RH 4) Refrigerants: R22, R134a, R404a, R407c 5) Power: DC 12V ± 10% 6) Rectangle wave 7) Operation way: 4 phase permanent magnetism, monopolar actuation 8) Excitation mode: 1 - 2 phase excitation, monopolar actuation 9) Excitation speed: 30 - 90pps 10) Flow direction: forward or backward 11) Pressure: 0 - 3.0MPa 12) Installation directions: coil upward, front, back, left, right ± 90 13) Max. operation pressure differential: 2.26MPa 14) Insulation resistance: above 100MΩ 15) Pressure differential to open valve in negative direction: 1.47MPa 16) Electrical strength: without breakdown or flashover when being tested by AC 600V for 1sec or AC 500V for 1min 17) Full open pulse: 480 18) Coil temperature increasing: below 60K 19) Tolerance referring to specifications for flow curve characteristics and data: ± 20% 20) Noise: below 60dB (A) 21) Leakage: below 400ml/min 22) Usage life: 100,000 cycles
