Rheem-Ruud 611031 Expansion Valve

The Rheem-Ruud 611031 Expansion Valve is a critical OEM replacement HVAC part engineered for precise refrigerant metering in specialized 3-ton systems. This high-efficiency thermal expansion valve (TXV) serves as the direct replacement for the legacy 61-26018-10 model, ensuring seamless retrofitting for field technicians. Designed for R-22 refrigerant applications, it features a 3/8-inch sweat inlet and outlet configuration for robust, leak-resistant connections. The integrated TXV with bleed port (10% bleed capacity) allows for pressure equalization during the off-cycle, facilitating easier compressor restarts even in high-static conditions. With 30 inches of capillary tube and an 18-inch equalizer tube connected via a 1/8-inch sweat O.D. external equalizer, this valve provides the responsive superheat control necessary to protect the compressor from liquid slugging while maximizing evaporator coil efficiency.

• Precise Refrigerant Control: The 611031 expansion valve maintains optimal superheat across varying load conditions to prevent coil icing.
• Direct Compatibility: Functionally replaces part number 61-26018-10 without requiring extensive piping modifications.
• Enhanced System Reliability: Features an internal check valve and factory-calibrated bleed port to support hard-start kits and low-torque compressors.
• Durable OEM Construction: Fabricated to withstand high-pressure differentials common in R-22 air conditioning and heat pump cycles.

Is the Rheem 611031 compatible with R-410A systems?
No, this specific Rheem-Ruud 611031 is calibrated for R-22 pressure-temperature curves. Using it with R-410A will lead to improper superheat and potential compressor failure.

Why does this TXV include a bleed port?
The bleed port allows a small amount of refrigerant to bypass the valve during the off-cycle, equalizing high and low-side pressures to assist compressors with starting under load.

What is the connection type for the external equalizer?
This model utilizes a 1/8-inch O.D. sweat connection, ensuring a permanent, vibration-resistant seal compared to flare fittings.
