Description
The Lennox 65G58 is a factory-engineered thermostatic expansion valve (TXV) designed for precise refrigerant metering and optimal system efficiency in residential and light-commercial cooling applications. With a 3/8″ x 5/8″ ODF connection configuration and a 1.5-ton rated capacity, this valve is purpose-built to deliver consistent superheat control across a wide range of operating conditions. The 30″ capillary tube provides flexible bulb placement during installation, making it easier to achieve proper thermal sensing contact on the suction line.
