Trane VAL12335 TXV

The Trane VAL12335 is a high-performance TR6 5T TXV (Thermostatic Expansion Valve) designed to provide mission-critical refrigerant metering for 5-ton HVAC systems. As a genuine OEM Trane expansion valve, this component is engineered to maintain precise superheat levels across varying load conditions, directly protecting the compressor from liquid slugging while maximizing evaporator efficiency. Constructed with a durable stainless steel body, the VAL12335 features a 3/8-inch inlet and a 1/2-inch outlet, rated for operating pressures up to 660 PSI. For technicians servicing American Standard or Trane air handlers and boxed coils, this R410A expansion valve serves as a direct-fit replacement to restore factory-spec subcooling and system equilibrium. Whether you are dealing with a starving evaporator or erratic hunting, the Trane 5 ton TXV ensures the balanced mass flow required for high-capacity residential and light commercial cooling applications.

• Precision Refrigerant Metering: Designed as a TR6 5T TXV to maintain optimal superheat and prevent compressor floodback.
• OEM Compatibility: Guaranteed fitment for Trane and American Standard equipment, cross-referencing with alternate part number X15111657500.
• Heavy-Duty Construction: Features a robust stainless steel design and 660 PSI pressure rating for long-term reliability in high-pressure R410A environments.
• Optimized Efficiency: Enables the system to achieve its rated SEER by precisely governing refrigerant flow based on evaporator load.

• What are the symptoms of a failing Trane VAL12335? Common indicators include frost on the evaporator coil, high superheat readings (underfeeding), or low suction pressure. If the valve is stuck open (?overfeeding), you may observe low superheat and potential liquid return to the compressor.
• Does this TXV include the sensing bulb and mounting hardware? Yes, this thermal expansion valve is a complete assembly designed for standard 5-ton refrigerant lines with 3/8" x 1/2" connections.
• Can I use this valve on non-Trane systems? While technically a refrigerant metering device, this is an OEM Trane expansion valve specifically calibrated for the pressure drops and flow rates of Trane and American Standard coils.
