description

The Trane / American Standard VAL08721 is an OEM 2-ton thermostatic expansion valve (TXV) designed for compatible HVAC air-conditioning and refrigeration systems. Featuring a 3/8-inch female sweat/brazed inlet connection and a permanent strainer, this valve regulates refrigerant flow entering the evaporator coil to support efficient cooling performance.

The VAL08721 TXV automatically adjusts refrigerant flow in response to evaporator operating conditions, helping maintain proper refrigerant superheat and consistent system performance. Its permanent strainer helps capture debris before it reaches the valve's metering components.

This factory replacement expansion valve is intended for HVAC equipment specifically requiring Trane part number VAL08721.

🛠️ HVAC Depot Pro Tip

When replacing the Trane VAL08721, verify the exact OEM part number and connection specifications before ordering.

Component: Thermostatic Expansion Valve (TXV)

The permanent strainer helps protect the metering valve from debris in the refrigerant circuit. During installation, technicians should follow proper system-cleanliness practices and protect the valve from excessive brazing heat.

Important: Not all 2-ton TXVs are interchangeable. Verify refrigerant compatibility, outlet connection size, equalizer configuration, and original equipment requirements before purchasing.

Installation should be performed by a qualified HVAC technician following proper refrigerant recovery, brazing, evacuation, leak testing, charging, and superheat verification procedures.

Before ordering, verify the complete indoor and outdoor equipment model numbers, serial numbers, refrigerant type, original TXV part number, and connection configuration.
