Rheem-Ruud 61-21922-02 Expansion Valve

The Rheem-Ruud 61-21922-02 Expansion Valve is a critical OEM flow control component engineered for 3-ton air conditioning systems utilizing R22 refrigerant. Designed for high-precision metering, this thermal expansion valve (TXV) modulates refrigerant flow into the evaporator, maintaining an optimal superheat to maximize heat transfer efficiency and protect the compressor from liquid slugging. It features a 3/8" x 1/2" sweat connection for reliable, leak-proof brazing in field installations and is equipped with a 30" capillary tube to allow for flexible mounting and accurate sensing bulb placement. This non-bleed type valve is compatible with both R-22 and R-407C systems, ensuring versatile performance in legacy cooling equipment. As a direct factory replacement part, this 3 ton R22 TXV ensures localized control of system pressures, maintaining the factory-specified performance standards required for Rheem and Ruud HVAC systems.

• Ensures precise refrigerant flow control to maintain specific superheat levels across varying load conditions.
• Features durable copper sweat connections (3/8" inlet, 1/2" outlet) for secure, permanent installation.
• Includes an extended 30-inch capillary tube for easy sensing bulb positioning on the suction line.
• Optimized for 3-ton residential and light commercial cooling applications to restore system efficiency.
• Genuine OEM Rheem-Ruud replacement part ensures drop-in compatibility and adherence to factory pressure specs.

Is this TXV compatible with R410A systems?
No, this specific valve is designed and calibrated for R22 and R407C refrigerants. Utilizing it with R410A will lead to improper metering and potential system failure.

Does this valve come with an external equalizer?
Yes, the 61-21922-02 includes a 1/4" sweat ID external equalizer connection to provide accurate sensing of the evaporator outlet pressure.

Can I use this valve on a 2.5-ton unit?
This valve is sized for a 3-ton capacity. For optimal performance and to avoid hunting or flooding the evaporator, always match the tonnage of the TXV to the capacity of the outdoor unit and indoor coil.
