12.5T Cooling Expansion Valve ATX-71110DUS for Refrigeration Unit

         This ATX-71110DUS thermostatic expansion valve is a core flow control component widely used in HVAC and commercial refrigeration systems. Designed for R404A refrigerant with 12.5 tons cooling capacity, it adopts S charging power head and 5/8×7/8 pipe connection specification. The brass valve body matches long capillary sensing bulb structure, which can automatically adjust refrigerant flow according to evaporator temperature, stabilize system superheat, avoid liquid return to compressor, optimize heat exchange efficiency, and extend the service life of refrigeration equipment. It features stable pressure sensing, sensitive temperature response and strong adaptability to variable load environments, being an essential replacement part for medium and low temperature refrigeration circulation loops.

• Matches R404A refrigerant, 12.5 tons rated cooling capacity
• S-type charging power head with high temperature sensing sensitivity
• Solid brass valve body, anti-corrosion and high pressure resistance
• 5/8×7/8 standard pipeline connection, convenient installation
• Automatically adjust refrigerant flow to prevent compressor liquid floodback
• Stable operation under variable load for medium-low temperature cooling systems
• Complete supporting capillary sensing bulb assembly
