ATX-71140DHS External Balance Cooling Valve

        This ATX-71140DHS thermostatic expansion valve is an essential throttling component widely used in HVAC and commercial refrigeration systems. It adopts external balance structure with S-type power head charge, matched for R22 refrigerant, rated capacity 22.6 tons, with 5/8×7/8 pipeline connection size. The precisely calibrated temperature sensing bulb and long capillary tube can stably sense evaporator outlet temperature, automatically adjust refrigerant flow to maintain ideal superheat, avoid liquid refrigerant backflow to compressors. Made of high-purity brass valve body and corrosion-resistant metal sensing assembly, it features stable pressure resistance, reliable flow regulation and long service life, perfectly meeting the precise cooling control demands of medium and large air conditioners, heat pumps and industrial cooling equipment.

• External balance design, stable control under high evaporator pressure drop
• S-type power head charge, sensitive and accurate temperature response
• Compatible with R22 refrigerant, rated capacity up to 22.6 tons
• High-purity brass valve body, anti-rust and high pressure resistance
• Standard 5/8×7/8 pipeline interface, easy installation and replacement
• Long capillary sensing tube, flexible layout for different equipment structures
• Effectively control superheat, prevent liquid slugging to extend compressor service life
