30.8T Refrigeration Expansion Valve ATX-12270DUS HVAC Part

         ATX-12270DUS thermostatic expansion valve is a heavy-duty refrigerant flow control component widely deployed in HVAC and large industrial commercial refrigeration circulation systems. This valve matches R404A refrigerant with a rated cooling capacity of 30.8 tons, equipped with S-type charging power head and standard 1×1 pipeline connectors. The integrated thick brass valve body and long coiled capillary sensing bulb automatically adjust refrigerant flow volume following evaporator operating temperature, stably lock system superheat value, completely avoid liquid refrigerant floodback to compressors, boost overall heat exchange efficiency and cut down breakdown risks of large cooling equipment. It delivers ultra-sensitive temperature feedback and stable continuous operation under heavy variable load conditions, acting as a universal replacement spare part for large-scale medium and low temperature refrigeration loops.

• Matches R404A refrigerant, rated cooling capacity reaches 30.8 tons
• S-type charging power head with ultra fast temperature sensing response
• Thick integrated solid brass valve body, excellent pressure & corrosion resistance
• Standard 1×1 pipeline interface, convenient field welding and installation
• Automatic refrigerant flow adjustment to eliminate compressor liquid floodback
• Stable long-term running performance under heavy fluctuating load
• Complete matched long coiled capillary sensing bulb assembly
