Rheem-Ruud 61-103652-03 Expansion Valve

The Rheem-Ruud 61-103652-03 Expansion Valve is a critical metering device designed specifically for 5-ton high-efficiency air conditioning and heat pump systems utilizing R410A refrigerant. This externally equalized Thermostatic Expansion Valve (TXV) features a 3/8" sweat inlet and includes a 30-inch external equalizer line to ensure precise superheat control across varying evaporator loads. Its construction utilizes a high-grade stainless steel power element and sensing bulb, designed to resist corrosion and maintain integrity under high-pressure applications. By modulating the flow of refrigerant based on suction line temperature, this direct-replacement HVAC expansion valve prevents liquid slugging and optimizes evaporator coil performance.

Key Technical Benefits

• System Precision: Provides accurate superheat management, ensuring the compressor operates within safe parameters while maximizing heat transfer.
• Durable Construction: Features braze-on (SWT) connections for leak-free installations and long-term vibration resistance in high-demand mechanical environments.
• OEM Compatibility: Specifically engineered for Rheem and Ruud split systems, simplifying the installation process for technicians by matching original equipment footprints.
• Enhanced Efficiency: Improves overall SEER ratings by maintaining the optimal refrigerant charge level during fluctuating thermal demands.

Common Installation Questions

Will this TXV work with older R22 systems?
No, this valve is calibrated specifically for R410A pressure-temperature characteristics. Using it with R22 will result in improper refrigerant flow and potential system failure.

What is the purpose of the 30-inch external equalizer line?
The external equalizer compensates for any pressure drop through the evaporator coil, allowing the 61-103652-03 TXV to sense the true pressure at the coil outlet for more accurate throttling.

Is this valve bi-flow compatible for heat pump applications?
Yes, this model is designed to handle the bidirectional flow requirements typically found in residential and light commercial heat pumps when configured with the appropriate check valves.
