Rheem-Ruud 61-26018-85 Expansion Valve

The Rheem-Ruud 61-26018-85 Expansion Valve is a critical OEM replacement part designed for technicians servicing R22 refrigeration systems. This 2.5-ton TXV features a balanced port design to maintain precise superheat control across varying load conditions, preventing liquid slugging and ensuring evaporator efficiency. Built with a 30-inch capillary tube and a 3/8-inch Chatleff inlet, it provides the necessary reach and secure fitment for Rheem and Ruud air handlers and heat pumps. The inclusion of a 7-inch external equalizer allows the valve to react accurately to pressure drops across the evaporator coil, optimizing the refrigerant flow for consistent cooling performance. This thermostatic expansion valve (Type CBBI) is engineered for durability in residential and light commercial applications, serving as a direct replacement for obsolete part numbers such as 61-26190-03 and 61-26019-05. When performance is non-negotiable, utilizing a genuine Rheem-Ruud TXV ensures the system maintains factory specifications and operational reliability.

• Precise Refrigerant Metering: Maintains constant superheat to maximize evaporator coil efficiency and protect the compressor from liquid floodback.
• Balanced Port Design: Compensates for fluctuating head pressures and ambient temperatures, making it ideal for units operating in extreme conditions.
• OEM Compatibility: Specifically engineered for Rheem-Ruud equipment, ensuring a perfect fit with Chatleff connections and sweat outlet fittings.
• Internal Check Valve: Optimized for heat pump applications that require bi-flow capability or integrated check valve assemblies.

Is this TXV compatible with R-410A systems?
No, this valve is specifically calibrated for R22 refrigerant. Using it with R-410A will lead to incorrect metering due to the significantly higher operating pressures of HFC systems.

What are the symptoms of a restricted or failing expansion valve?
Technicians typically observe low suction pressure, high superheat at the evaporator outlet, or frosting on the expansion valve inlet. These issues often stem from debris or moisture in the system.

Does this valve include the sensing bulb mounting hardware?
This is the TXV body with the 30" capillary tube and sensing bulb; it is recommended to use proper copper straps to ensure the bulb has 100% surface contact with the suction line for accurate sensing.
