ATX-12220DHS R22 Thermal Expansion Valve 35.8 Ton HVAC Part

        ATX-12220DHS thermal expansion valve acts as a core throttling component for HVAC and industrial refrigeration systems, compatible with R22 refrigerant with a rated cooling capacity of 35.8 tons. Equipped with S-type charged power head and standard 1×1 pipeline connection, it accurately regulates liquid refrigerant flow entering the evaporator by sensing real-time evaporator outlet temperature. The integrated brass valve body delivers stable pressure resistance and excellent thermal conductivity, which precisely balances the superheat of refrigeration circuits to prevent compressor liquid floodback, optimize overall cooling efficiency, and support continuous stable operation of small and medium cooling equipment.

• 35.8 ton standard cooling capacity, stable throttling performance for small & medium cooling systems
• S-charged power head with high-precision temperature sensing response
• Solid brass integrated valve body, outstanding pressure resistance and heat conduction
• Standard 1×1 pipeline interface, simple installation and daily maintenance
• Accurate superheat adjustment, avoid liquid slugging damage to compressors
• Wide compatibility with multiple HVAC and commercial refrigeration equipment
