Description
The Carrier EA36YJ135 is an OEM thermal expansion valve (TXV) engineered for use in Carrier refrigeration and air conditioning systems. Designed to deliver precise, automatic control of refrigerant flow into the evaporator coil, this valve helps maintain optimal superheat levels — protecting the compressor and maximizing system efficiency across a wide range of operating conditions.
How It Works
The thermal expansion valve senses evaporator outlet temperature and pressure, then modulates refrigerant flow accordingly. By maintaining the correct superheat, the TXV ensures the evaporator coil is fully utilized without allowing liquid refrigerant to return to the compressor — a critical safeguard for system longevity.
Key Features
- OEM Carrier replacement thermal expansion valve
- Provides precise refrigerant metering for consistent superheat control
- Protects the compressor from liquid slugging and floodback
- Engineered for direct OEM fit in compatible Carrier equipment
- Supports efficient system operation and energy performance
- Durable construction for long-term reliability in demanding HVAC applications
Applications
- Carrier residential and commercial air conditioning systems
- Carrier heat pump systems
- Refrigeration equipment requiring OEM-specified TXV replacement
Why Choose an OEM TXV?
Using a genuine Carrier OEM thermal expansion valve ensures proper fit, function, and compatibility with your system’s refrigerant circuit. Aftermarket substitutes may not meet the precise flow ratings or pressure specifications required by your equipment, potentially voiding warranties or reducing system performance. The EA36YJ135 is the correct factory-specified replacement, giving technicians confidence in every installation.
