Air conditioner flow control three-way valve

The air conditioning three-way valve is a key component for switching and controlling the refrigerant flow in air-conditioning systems. Its core advantage lies in "precise flow control + mode adaptation." It adopts a high-purity, refrigerant-resistant brass or stainless steel one-piece cast valve body and a built-in precision ceramic valve core or copper alloy valve core. By rotating the valve core, the refrigerant flow direction can be switched in two directions and the flow rate can be adjusted in a stepped manner. It adapts to the refrigerant flow requirements when switching between cooling and heating modes of the air conditioner. At the same time, the valve core and valve seat are mirror-polished and combined with refrigerant-resistant fluororubber sealing rings to form a double sealing structure. It can withstand a wide temperature range of -40℃~120℃ for a long time, ensuring stable operation. Core selling points directly address the needs of air conditioning systems: For complex systems like multi-split units and central air conditioners, some models integrate an electronic control module, supporting remote and precise flow control and adapting to intelligent air conditioning control. The valve body features a streamlined flow path design to reduce refrigerant transport energy consumption. The interface specifications cover mainstream air conditioning pipes from DN6 to DN20, supporting welding and threaded connection methods, without the need for additional adapters. Some models include a maintenance port for convenient system pressure testing and refrigerant replenishment without valve body disassembly. Application scenarios cover a wide range of air conditioning systems, including residential wall-mounted/cabinet air conditioners, commercial central air conditioners, multi-split units, ducted units, and heat pump air conditioners. Whether establishing refrigerant circuits during new unit installation, controlling mode switching in existing equipment, or disconnecting and repairing pipes during troubleshooting, the valve can effectively perform its functions. It is particularly suitable for residential and commercial scenarios that require frequent switching between cooling and heating modes, helping to improve the efficiency and stability of air conditioning systems.
