Reznor 220555 Valve

The Reznor 220555 Thermal Expansion Valve (TXV) is a critical OEM replacement part designed for high-capacity commercial HVAC systems. Engineered for 6-ton cooling applications, this thermostatic expansion valve features a 5/8" inlet and a 7/8" outlet with ODF sweat connections to ensure a secure, leak-free integration into the refrigerant line. Utilizing a precision-tuned sensing bulb and capillary tube, the 220555 monitors the superheat at the evaporator outlet, modulating the flow of refrigerant to match the varying cooling load of the building.

This HVAC expansion valve is essential for maintaining energy efficiency and protecting the compressor from liquid slugging. By maintaining optimal superheat levels, the valve prevents liquid refrigerant from returning to the suction line, thereby extending the service life of major industrial refrigeration components. As a genuine Reznor part, it is built to original factory specifications, ensuring compatibility with specific rooftop units and unit heaters where precise metering is required for peak performance.

• Specifically engineered for 6-ton HVAC equipment providing precise refrigerant metering.
• Protects against compressor damage by preventing liquid refrigerant return.
• Improves overall system efficiency and stability across varying thermal loads.
• Durable OEM construction enables a seamless fit and long-term reliability in commercial environments.
• Optimizes the evaporator coil's thermal exchange by maintaining a stable superheat.

What is the capacity and connection size for this valve?
The Reznor 220555 is a 6-ton TXV featuring a 5/8" inlet and 7/8" outlet for standard ODF sweat installations.

How do I know if my expansion valve has failed?
Contractors typically look for symptoms such as high superheat, frost buildup on the evaporator, or a compressor running constantly without cooling effectively. A loss of charge in the sensing bulb is a frequent failure point that prevents the valve from opening.

Is this an adjustable expansion valve?
Yes, this professional-grade thermostatic expansion valve allows technicians to fine-tune the superheat settings via the adjustment stem to meet specific system operational requirements.
