HVAC ATX-12420DUS 47.9T Refrigeration Expansion Valve

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

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