Rheem-Ruud 61-21922-39 TXV

Maintaining precise superheat is critical for the longevity of any 3-ton condenser, and the Rheem-Ruud 61-21922-39 TXV is the specific OEM solution for R-22 systems requiring a 3/8" x 3/8" configuration. As a technician, you know that field-converted or "universal" valves often lead to hunting issues or improper evaporator loading. This thermal expansion valve is balanced-port engineered, ensuring stable refrigerant flow across varying ambient temperatures and load conditions. The 30-inch capillary tube provides the necessary reach for secure sensing bulb placement on the suction line, preventing the premature liquid slugging common in older R-22 units.

Whether you are performing a dry-charge unit repair or a scheduled evaporator coil maintenance, utilizing a genuine Rheem replacement part ensures the internal flow orifices match the manufacturer's original specification. This HVAC expansion valve is a direct drop-in for 36,000 BTU systems, designed to optimize heat transfer efficiency and protect the compressor from low-pressure drop-outs in legacy cooling applications.

• OEM Precision: Specifically calibrated for R-22 refrigerant systems to eliminate the guesswork of manual superheat adjustments.
• Direct Compatibility: Features 3/8" inlet and outlet connections for seamless integration into standard 3-ton liquid lines and distributors.
• Enhanced Reach: The 30" capillary tube allows for professional bulb mounting even in cramped air handler or furnace coil cabinets.
• System Reliability: Helps prevent evaporator freeze-ups and compressor overheating by maintaining a consistent TXV superheat.

Is this valve compatible with R-410A systems?
No, this specific model is cross-referenced and orifice-sized exclusively for R-22 systems. Using this on high-pressure HFC systems will result in severe performance failure.

What is the tonnage rating for the 61-21922-39?
This is a dedicated 3-ton TXV. For 2-ton or 4-ton Rheem systems, please verify the specific part number as orifice sizes vary by capacity.

Does it include the sensing bulb mounting hardware?
Most OEM Rheem valves come with the necessary straps or clips, but we recommend having standard copper sensing bulb straps on hand for a secure suction line thermal bond.
