lectronic Expansion Valve

Chinese factory SANHENG Electronic Expansion Valve in stock. It’s mainly used in refrigeration and freezing systems to achieve automatic adjustment of refrigerant flow. When LPF series electronic expansion valves are completely closed, the leakage in the system is low, and the effect is equal to that of solenoid valves. Therefore, LPF series electronic expansion valves can completely replace solenoid valves in refrigeration and freezing, saving installation space and cost.The use of Electronic Expansion Valve improves the energy efficiency of inverter compressors, enables rapid temperature regulation and improves the seasonal energy efficiency of the system.

Product Description

SANHENG is a China-based factory of Electronic Expansion Valve. The Electronic Expansion Valve is a speed type, which is used in intelligent control inverter type air conditioners. The advantages of electronic expansion valves are: large flow rate adjustment range; high control accuracy; suitable for intelligent control; and can be applied to rapid changes in refrigerant flow rate with high efficiency.The opening of the Electronic Expansion Valve can be adapted to the speed of the compressor, so that the amount of refrigerant delivered by the compressor can be matched with the amount of liquid supplied by the valve, so that the capacity of the evaporator can be maximised and the optimal control of the refrigeration system can be achieved.
Advantages of Electronic Expansion Valve:
1)Wide range of flow rate adjustment;
2)High control precision;
3)Suitable for intelligent control;
4)Can be applied to rapid changes in refrigerant flow with high efficiency.

·Unidirectional flow, low internal leakage when the valve is closed, the effect is equivalent to a solenoid valve for oil-free systems.(Excluding SLPF 45-62)
·Inlet tube with built-in filter.(Excluding SLPF 45-62)
·Withstands 9MPa working pressure, suitable for CO, system suitable for controllers.
