External Balanced Expansion Valve Model ATX-71110DHS for Refrigeration

      This thermal expansion valve is a core throttling component widely applied in HVAC and industrial refrigeration systems, model ATX-71110DHS, compatible with R22 refrigerant with a cooling capacity of 17.8 tons. It adopts external balance structure with S-type power head charging, preset 5℃ superheat, and matched 5/8×7/8 pipeline connections. As the vital flow control part of refrigeration circulation, it precisely regulates refrigerant flow by sensing evaporator outlet temperature, balances system pressure difference, stabilizes evaporator heat exchange efficiency, effectively prevents liquid refrigerant backflow to the compressor, and ensures stable, safe and energy-efficient operation of the whole HVAC refrigeration system. The all-copper valve body with fine machining delivers excellent pressure resistance and sealing performance, adapting to long-duration continuous operation of commercial and industrial HVAC equipment under variable load conditions.

• External balance structure, stable performance under long pipeline & large pressure drop conditions
• S-type power head charging, factory pre-set 5℃ superheat, convenient on-site installation
• 17.8 ton rated cooling capacity, perfect matching R22 refrigerant system
• Integral brass valve body, high pressure resistance, corrosion resistance and reliable sealing
• Standard 5/8×7/8 pipeline connector, easy piping assembly
• Sensitive temperature sensing capillary, rapid response to evaporator load changes
• Effectively avoids liquid slugging, extends compressor service life
• Compact integrated structure, convenient maintenance and replacement
