ATX-34045DHS S Charge TXV R22 7Ton Air Conditioner Throttle Valve

         ATX-34045DHS thermostatic expansion valve is a core throttling component designed for R22 refrigerant, with 7.0 tons rated cooling capacity and S-charge power head, widely applied to HVAC and commercial refrigeration circulation systems. Constructed with integrated brass valve body and long stainless steel coiled capillary tube, it automatically adjusts refrigerant supply volume by sensing evaporator outlet temperature to stabilize superheat value, boost heat exchange efficiency and prevent liquid slugging damage to compressors. Equipped with standard welded pipeline connectors, this valve features stable pressure resistance and flexible adaptability to variable load operating conditions, delivering consistent and precise flow regulation during long-time continuous running of HVAC cooling equipment, cold storage and air conditioning units.

• S-type charging power head, stable flow control within wide evaporation temperature range
• Integrated brass valve body, corrosion resistant and high pressure resistant for long service life
• Standard welded pipeline interface, tight assembly and low refrigerant leakage risk
• 7.0Ton rated cooling capacity, ideal for small & medium HVAC refrigeration units
• Automatic superheat adjustment structure, effectively protect compressor from liquid slugging
• Complete stainless steel coiled capillary sensing tube, sensitive temperature detection and easy installation
• Exclusive compatibility with R22 refrigerant, fit most conventional commercial cooling systems
