Trane VAL5036 Valve

Field technicians and contractors know that maintaining precise superheat is critical for the longevity of large-tonnage systems. The Trane VAL5036 thermal expansion valve is a heavy-duty 20-ton thermostatic expansion valve designed for high-capacity light commercial and industrial HVACR applications. This OEM Trane expansion valve features 7/8" x 1 3/8" ODF sweat connections, ensuring a secure, leak-resistant fit in the liquid line and evaporator inlet. Engineered to handle the rigorous demands of 20-ton circuits, the VAL5036 utilizes a 5-foot capillary tube and a sensing bulb to provide accurate feedback, protecting the compressor from liquid slugging while maximizing evaporator efficiency. By precisely regulating refrigerant flow based on heat load, this valve prevents fluctuating discharge temperatures and ensures the refrigeration cycle remains balanced even under extreme ambient conditions. When performing a TXV replacement, the VAL5036 serves as the direct Trane HVAC replacement part for ensuring refrigerant flow control meets original factory specifications, maintaining the performance standards expected of Trane equipment.

• Precise Superheat Regulation: Optimized for 20-ton systems to prevent compressor flooding and ensure efficient heat transfer.
• Durable Construction: Features 7/8" x 1 3/8" ODF solid copper connections for reliable brazing and long-term joint integrity.
• Extended Reach: The 5-foot capillary tube provides the necessary flexibility for proper sensing bulb placement on suction lines.
• Industrial Grading: Built to withstand the high-pressure environments of R-410A or R-22 systems depending on original equipment configuration.

• What are the symptoms of a failing VAL5036 expansion valve? Common indicators include an iced-over evaporator coil, high suction pressure combined with low superheat, or inconsistent cooling performance where the air alternates between cold and warm.
• Is this valve compatible with R-410A systems? Yes, this specific high-tonnage Trane TXV is designed for modern high-pressure refrigerants, provided the power element and orifice size match the system’s capacity.
• Why is the 5-foot capillary length important? The 5-foot lead allows for the sensing bulb to be mounted adequately away from the valve body on the suction header, ensuring it reads true vapor temperature without being influenced by the liquid line's heat.
