HVAC ATX-12330DUS Refrigeration Expansion Valve 37.6T

      This ATX-12330DUS thermostatic expansion valve is a core throttle component widely applied in HVAC and commercial refrigeration systems, designed for R404A refrigerant with 37.6 tons cooling capacity, S-type charge and 1×1 solder joint connection. Adopting full brass valve body and stainless steel capillary power head, it delivers stable superheat adjustment, compatible with medium-low temperature cold storage, freezer and chiller units. Its built-in external equalizer ensures accurate flow control under fluctuating evaporator pressure, improving overall system energy efficiency and running stability for long-term industrial HVAC cooling equipment.

• Matches R404A refrigerant, 37.6T rated cooling capacity
• S-type power head charge for stable low-temp adjustment
• Full brass valve body, anti-corrosion & long service life
• 1×1 solder inlet/outlet connection, easy field installation
• Built-in external equalizer for precise flow regulation
• Stainless steel capillary tube power head, sensitive temperature sensing
• Perfect fit for HVAC, cold storage and chiller refrigeration systems
