Rheem-Ruud PD619066 Expansion Valve Kit

The Rheem-Ruud PD619066 Expansion Valve Kit is the essential OEM thermal expansion valve (TXV) solution for 3-ton R410A cooling systems. Engineered as a high-precision flow control component, this TXV kit regulates refrigerant flow into the evaporator coil based on the thermal load, preventing compressor slugging and ensuring consistent superheat under varying conditions. This model is a direct functional replacement for the RXCT-FBB, specifically designed for use in Rheem and Ruud RCFM, RCSM, RCFL, and RCSL indoor coil series. Featuring a 3/8-inch ODF sweat inlet and a distributor-ready outlet, the PD619066 provides accurate metering required to maintain system efficiency and seasonal performance ratings. For technicians performing R410A expansion valve replacement, this kit contains the necessary adapters to restore factory-spec pressure drops and refrigerant distribution, making it an indispensable HVAC replacement part for ensuring long-term reliability in residential and light commercial air conditioning applications.

• OEM Compatibility: Precision-matched as the direct replacement for RXCT-FBB in Rheem and Ruud equipment.
• Precise Superheat Control: Optimizes refrigerant state to protect the compressor and maximize evaporator efficiency.
• Optimized for R410A: Calibrated for the high-pressure characteristics of modern R410A systems.
• Application Versatility: Fits a broad range of 3-ton air handlers and cased coils including RCFM and RCSL series.
• Professional Grade: All-metal construction designed for sweat-in installation and durable field service.

Is the PD619066 a direct swap for the RXCT-FBB?
Yes, the PD619066 is the designated successor and direct replacement for the legacy RXCT-FBB expansion valve kit.

Does this TXV kit work with R22 systems?
No, this valve is specifically calibrated for R410A refrigerant pressures and should not be used in R22 or alternative refrigerant systems.

Are additional copper adapters included in the kit?
Yes, the kit typically includes the distributor and specific adapters required to facilitate a 3/8-inch ODF inlet connection for standard 3-ton coil configurations.
