Trane VAL8801 Thermostatic Expansion Valve Ton - 3/8x1/2 R410A 5

The Trane VAL8801 is a thermostatic expansion valve (TXV) designed for R410A refrigerant systems with a 5-ton cooling capacity. This precision metering device regulates refrigerant flow into the evaporator coil, ensuring optimal system performance and efficiency in residential and light commercial HVAC applications.

Key Specifications:

• Inlet connection: 3/8 inch ODF (flare)
• Outlet connection: 1/2 inch ODF (flare)
• Refrigerant type: R410A
• Nominal capacity: 5 tons
• OEM Trane replacement part

This expansion valve maintains proper superheat control across varying load conditions, helping to prevent liquid refrigerant from entering the compressor while maximizing cooling capacity. The TXV automatically adjusts refrigerant flow based on evaporator load, making it superior to fixed orifice devices in applications with fluctuating conditions.

Applications:

• Trane air conditioning systems
• Split system heat pumps
• Package units
• Replacement and retrofit applications

Professional installation is required. The valve includes a replaceable sensing bulb that must be properly mounted to the suction line for accurate operation. Compatible with Trane and American Standard equipment designed for R410A refrigerant.
