Zhejiang Xuanyuntong Refrigeration Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of electronic expansion valve in China, also supports custom service. Welcome to wholesale high quality electronic expansion valve at competitive price from our factory.
This electronic expansion valve is composed of electromagnetic coil, valve core, valve body, sensor and other components, driven by stepping motor or servo motor, which can realize stepless adjustment. The opening adjustment is accurate to tiny scales, which can quickly respond to system load changes and real-time match the refrigerant demand. It has excellent sealing performance, adopts a precision spherical sealing structure, which can effectively prevent refrigerant leakage, and is suitable for various common refrigerants such as R22, R410A, R134a and R32. It can withstand the high and low temperature and high pressure working conditions of the refrigeration system, with a working temperature range of -50℃ to 120℃ and a working pressure of up to 15-40MPa, and runs stably without jamming.
The electronic expansion valve has intelligent regulation capability, which can be linked with the controller of the refrigeration system, automatically adjust according to parameters such as evaporation temperature and condensation pressure, realize precise throttling, greatly improve the refrigeration efficiency of the refrigeration system and reduce energy consumption. The valve body is made of high-quality corrosion-resistant materials such as stainless steel and brass, with outstanding oxidation and moisture resistance, adapting to the low-temperature and humid working environment of the refrigeration system. It has a compact structure, small volume and convenient installation, and can be flexibly adapted to the pipelines of different specifications of refrigeration equipment.
