Trane VAL8801 TXV

The Trane VAL8801 is a high-performance 5-ton thermostatic expansion valve engineered for precise refrigerant metering in R410A residential and commercial air handlers. This OEM expansion valve, also identified by part number D154636P07, features 3/8 x 1/2 ODS connections and is designed to maintain optimal superheat across varying load conditions. It serves as a direct replacement for Trane TXV kit components, ensuring the evaporator coil operates at peak efficiency while preventing liquid slugging to protect the compressor. This non-bleed, mechanised hardware is critical for systems requiring consistent subcooling and pressure regulation, especially when servicing units under high thermal stress.

• Matches Trane VAL8801 5 ton specifications for exact fit and performance.
• Supports R410A refrigerant systems with balanced port design to minimize hunt.
• Compatible with 3/8 inch inlet and 1/2 inch outlet brazed line sets.
• Functions as a direct electrical and mechanical equivalent to D154636P07.
• Engineered to optimize heat transfer efficiency in Trane air handlers and heat pumps.

Is the VAL8801 compatible with older R22 systems?
No, this R410A thermal expansion valve is calibrated specifically for the pressure-temperature relationship of R410A. Using it with other refrigerants will lead to improper metering and potential compressor damage.

What is the difference between VAL8801 and D154636P07?
These parts are identical in form, fit, and function. VAL8801 is the common service part number used by technicians to replace the factory-installed D154636P07 valve.

Does this TXV include the internal check valve for heat pump applications?
Yes, this Trane 5 ton TXV is designed to facilitate bidirectional flow and proper metering during cooling cycles while allowing bypassed flow during the heating cycle in compatible heat pump configurations.
