Armstrong Furnace A2TXV01 Expansion Valve

The Armstrong Furnace A2TXV01 is a high-precision thermostatic expansion valve (TXV) engineered specifically for Armstrong Air HVAC equipment. Designed for residential air conditioning and heat pump applications, this OEM replacement part handles capacities ranging from 1.5 to 3 tons. It features a 3/4-inch inlet and a 3/8-inch outlet for seamless integration with existing line sets. This valve utilizes R-22 refrigerant (though internal mechanics of newer equivalents may support broader configurations, always check original equipment specifications) to maintain a constant evaporator superheat across varying load conditions. By modulating the flow of refrigerant into the coil, the A2TXV01 expansion valve prevents liquid slugging of the compressor while maximizing heat transfer efficiency. For technicians, the robust construction ensures reliable performance in demanding environments, making it a critical component for restoring system balance and achieving optimal SEER ratings. Trust this official Armstrong Air valve for accurate temperature regulation and long-term equipment durability.

• Precise Refrigerant Metering: Automatically adjusts flow to maintain the correct superheat, protecting the compressor and enhancing efficiency.
• OEM Compatibility: Specifically designed as a direct Armstrong Furnace A2TXV01 replacement, ensuring perfect fitment without field modifications.
• Versatile Capacity: Optimized for systems ranging from 1.5 to 3 tons, providing flexibility for various residential tonnage requirements.
• Enhanced System Reliability: Durable build quality minimizes the risk of valve sticking or diaphragm failure in high-cycle applications.

What are the symptoms of a failing A2TXV01 expansion valve?
Common signs include a frozen evaporator coil, high suction pressure with low discharge pressure (if stuck open), or a compressor that runs constantly without providing adequate cooling (if stuck closed).

Is the Armstrong A2TXV01 compatible with R-410A systems?
The A2TXV01 is traditionally specified for R-22 refrigerant systems. For R-410A applications, refer to the A4TXV series or verify with the equipment’s data plate to ensure matching pressure/temperature curves.

How do I confirm this is the correct TXV for my 2.5-ton unit?
Check the model number on your existing air handler or evaporator coil. This valve covers a range including 1.5, 2, 2.5, and 3-ton capacities, provided the connection sizes (3/4x3/8) and refrigerant type match your specs.
