HVAC ATX-12420DUS 47.9T Refrigeration Expansion Valve

           The ATX-12420DUS thermostatic expansion valve is a core throttling component designed for HVAC and commercial refrigeration systems, specially matched with R404A refrigerant, with rated cooling capacity of 47.9 tons and S-type power head charge. It adopts full anti-corrosion brass valve body and stainless steel coiled capillary power head, equipped with built-in external equalizer to stabilize superheat adjustment. It maintains precise refrigerant flow control under fluctuating evaporator pressure, effectively improving energy efficiency and long-term stable operation for medium-low temperature cold storage, commercial freezer, industrial chiller and all kinds of industrial HVAC cooling equipment.

• Matches R404A refrigerant, rated cooling capacity up to 47.9 tons
• S-type power head charge for stable low-temperature regulation performance
• Integral solid brass valve body, corrosion resistant and long service life
• 1×1 solder inlet and outlet ports, simple field welding installation
• Built-in external equalizer for accurate refrigerant flow control
• Stainless steel coiled capillary power head, sensitive temperature sensing response
• Wide compatibility with HVAC, cold storage and industrial chiller systems
