Lennox Y8737 R410A 3.5-5Ton Thermal Expansion Valve

The Lennox Y8737 is a thermal expansion valve (TXV) designed for use in HVAC systems that utilize R410A refrigerant, a common coolant in air conditioners. Unlike valves controlling water flow, TXVs are self-regulating. They use a sensor to monitor refrigerant temperature within the system. By responding to temperature changes, the TXV automatically adjusts the flow of refrigerant. This controlled flow ensures optimal system performance and protects the compressor from damage caused by excess refrigerant. Installed with a standard 3/4 inch connection, the Y8737 is suitable for air conditioning units with capacities between 3.5 and 5 tons. It can withstand pressure up to 660 psi and functions within a temperature range of 15°F to 60°F. Some of the benefits of using the Lennox Y8737 TXV include: efficient refrigerant control, optimized system performance, and protection of compressor components.
