Zhejiang Xuanyuntong Refrigeration Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of refrigeration system expansion valve in China, also supports custom service. Welcome to wholesale high quality refrigeration system expansion valve at competitive price from our factory.
The refrigeration system expansion valve adopts a precise flow control structure, which can automatically adjust the opening according to the superheat of the refrigerant at the outlet of the evaporator, ensuring that the refrigerant evaporates fully in the evaporator, avoiding "liquid hammer" or "liquid shortage" phenomena, and protecting the compressor from safe operation. Its materials are mostly corrosion-resistant and high-temperature-resistant brass or stainless steel, suitable for different refrigerant types and working condition requirements, with a compact structure, convenient installation and no complex maintenance.
The refrigeration system expansion valve as the "flow control valve" of the refrigeration system, it is widely used in various refrigeration equipment such as air conditioners, cold storages and industrial refrigeration. It can effectively coordinate the working rhythm of the condensation system and the evaporation system, improve system energy efficiency, reduce energy loss, and is one of the core components to ensure the efficient, stable and low-carbon operation of the refrigeration system.
