The core difference between thread welded refrigeration solenoid valve and other common refrigeration solenoid valves on the market lies mainly in its unique and firm pipe connection method and the comprehensive performance advantages it brings. Although all refrigeration solenoid valves are based on the electromagnetic principle to control the on and off of refrigerants in their core functions, thread welded refrigeration solenoid valves completely eliminate the long-standing pain point of interface leakage in traditional refrigeration systems by directly tightening the valve body interface and the pipeline with threads and then welding and curing.
In contrast, common flange connections, ferrule connections or ordinary threads plus sealing materials can ensure sealing even when they are first installed, but the risk of leakage increases significantly when the system faces hot and cold cycles, vibration shocks or aging of sealing materials during long-term operation. This not only causes refrigerant loss and energy efficiency reduction, but also affects the environmental protection and operation safety of the system.
The welded seal of the threaded welded refrigeration solenoid valve creates a truly "integrated" sealed connection point, which is as strong as the pipeline itself, and has almost no weak links of conventional interfaces. This makes it perfect for high-vibration environments (such as ships, mobile equipment or industrial compressors), high-pressure occasions, and applications with extremely stringent sealing requirements (such as systems using new environmentally friendly refrigerants with extremely low global warming potential but prone to leakage).
The cost of this design is that welding skills are required during installation, and later maintenance and disassembly are relatively complicated, requiring cutting of pipes. However, for systems that pursue ultimate reliability and eliminate minor leaks, the long-term maintenance-free and high safety guarantees provided by the threaded welded refrigeration solenoid valve make it an irreplaceable choice. In general, the threaded welded refrigeration solenoid valve represents the highest level of connection reliability and is the key guarantee for ensuring long-term stable, efficient and safe operation of the system in specific critical application scenarios.
