Lennox 73W83 Reversing Valve
The Lennox 73W83 Reversing Valve is an OEM-engineered component designed to control refrigerant flow direction for critical heat pump applications. Manufactured by Sanhua (model SHF-14-46) for Lennox systems, this 4-way reversing valve features 1/2-inch x 3/4-inch solder connections with a high-durability brass body and stainless steel internal slide mechanism. Built to operate on a 24 VAC solenoid at 50/60Hz, it provides precise switching between heating and cooling modes. This valve is fully compatible with modern refrigerants such as R-410A and R-22, ensuring reliable performance during seasonal load shifts. For technicians performing a Lennox reversing valve replacement, the 73W83 offers a direct-fit specification (Manufacturer Part # 100145-10) that eliminates the need for auxiliary piping modifications in standard residential and light commercial configurations.
Key Benefits- Broad Compatibility: Seamlessly integrates with Lennox heat pump parts and HVAC systems requiring 1/2" discharge and 3/4" suction lines.
- Optimized Performance: Features Viton seals to prevent refrigerant blow-by and improve system efficiency.
- Rugged Construction: Designed with a 7-1/4" overall length and built to withstand high-pressure nitrogen testing and long-term cycling.
- OEM Reliability: Ensures exact electrical matching for 24V thermostat control circuits, reducing the risk of solenoid chatter or failure.
What are the connection sizes for the 73W83?
This valve uses a 1/2" ID discharge/suction port and 3/4" ID ports for the remaining connections, standard for many residential split systems.
Can the solenoid coil be replaced separately?
Yes, the 24 VAC solenoid coil (part number 1472553843 often found with this assembly) is removable, allowing for electrical repairs without breaking into the refrigerant circuit.
Is this valve compatible with R-410A systems?
Yes, the Sanhua SHF series is rated for high-pressure refrigerants, including R-410A, making it a versatile HVAC reversing valve for modern equipment.
