Electronic Expansion Valve
Applications: electronic expansion valve is used for home air conditioners, mainlyinstalled in the converter air conditioning system, to regulate the refrigerantflow automatically. Hence, the air conditioning system will keep working withthe best capacity, quick cooling, accurate temperature controlling and power saving.The electric expansion valve can also be used for other kind of flow controllingdue to automatic controlling performance of the refrigerant flow under coolingand heating conditionsSpecifications:1) Air flow: 310NL/min (2.5MPa), 480NL/min (above 3.5MPa)2) Capacity: 1.5USRT / 5.3kW3) Flow feature: BTechnical parameters:1) Ambient temperature: -30 - +60oC2) Flow temperature: -30 - +90oC3) Ambient humidity: below 95% RH4) Refrigerants: R22, R134a, R404a, R407c5) Power: DC 12V ± 10%6) Rectangle wave7) Operation way: 4 phase permanent magnetism, monopolar actuation8) Excitation mode: 1 - 2 phase excitation, monopolar actuation9) Excitation speed: 30 - 90pps10) Flow direction: forward or backward11) Pressure: 0 - 3.0MPa12) Installation directions: coil upward, front, back, left, right ± 9013) Max. operation pressure differential: 2.26MPa14) Insulation resistance: above 100MΩ15) Pressure differential to open valve in negative direction: 1.47MPa16) Electrical strength: without breakdown or flashover when being testedby AC 600V for 1sec or AC 500V for 1min17) Full open pulse: 48018) Coil temperature increasing: below 60K19) Tolerance referring to specifications for flow curve characteristics anddata: ± 20%20) Noise: below 60dB (A)21) Leakage: below 400ml/min22) Usage life: 100,000 cycles
