Rheem-Ruud 61-26018-99 TXV
The Rheem-Ruud 61-26018-99 is a high-precision 4-ton thermostatic expansion valve designed specifically for R-22 refrigerant systems. This OEM Chatleff x 3/8" ODF TXV is engineered to maintain optimal superheat at the evaporator coil, ensuring maximum system efficiency and compressor reliability. As a direct replacement for the 61-26190-05, this valve ensures seamless integration into existing air handler and heat pump configurations without the need for extensive field modifications. By utilizing a balanced port design, the 61-26018-99 compensates for varying pressure drops across the valve, providing stable liquid flow control even during fluctuating ambient conditions. For contractors performing retrofits or emergency repairs on legacy R-22 equipment, this HVAC expansion valve offers the exact mechanical specifications required to restore factory-standard cooling performance. The internal construction features high-grade materials to resist corrosion and mechanical fatigue in demanding residential and light commercial applications.
Key Features and Technical Benefits
- Direct OEM Replacement: Engineered as the specific drop-in successor for the legacy 61-26190-05 part number.
- Precise Superheat Control: Maintains consistent evaporator flooded conditions to prevent liquid slugging and improve heat transfer.
- Standard Connections: Features a Chatleff inlet and 3/8" ODF outlet for standard fitment in Rheem and Ruud evaporator coils.
- R-22 Compatibility: Calibrated specifically for the pressure-temperature characteristics of R-22 refrigerant circuits.
- 4-Ton Capacity: Sized for high-output residential split systems, ensuring adequate mass flow during peak demand.
Common Questions
Is the 61-26018-99 compatible with R-410A systems?
No, this valve is calibrated specifically for the R-22 pressure-temperature curve. Using this on an R-410A system will lead to improper refrigerant metering and potential compressor damage.
Does this TXV require a separate adapter for the Chatleff fitting?
This unit features a standard Chatleff nut. If your existing manifold or liquid line matches the Chatleff x 3/8" ODF specification, no additional adapters are required for installation.
Can I use this to replace the 61-26190-05?
Yes, the Rheem-Ruud 61-26018-99 is the official direct replacement part for the discontinued 61-26190-05, maintaining identical form, fit, and function.
