Rheem-Ruud 61-105338-90 Thermal Expansion Valve TXV - Kit

The Rheem-Ruud 61-105338-90 is a genuine OEM thermal expansion valve (TXV) kit designed for Rheem and Ruud residential and commercial HVAC systems. This critical component regulates refrigerant flow into the evaporator coil, maintaining optimal system efficiency and protecting the compressor from damage.

Key Features:

• Controls refrigerant flow based on superheat temperature for optimal system performance
• Includes complete thermal expansion valve assembly with sensing bulb and capillary tube
• Helps prevent compressor flooding and overheating by maintaining proper refrigerant metering
• Improves SEER efficiency ratings compared to fixed orifice systems
• Genuine Rheem-Ruud factory replacement part ensuring proper fit and function
• Professional installation by certified HVAC technician required

The TXV uses a temperature-sensing bulb attached to the evaporator outlet to create a feedback loop that automatically adjusts refrigerant flow as cooling demand changes. This maintains consistent superheat levels and maximizes heat transfer efficiency while protecting critical system components. Ideal for replacement of failed expansion valves or system upgrades requiring improved refrigerant control.
