Description
The Carrier EA36YD199 is an OEM thermostatic expansion valve (TXV) engineered to deliver precise refrigerant metering and optimal system performance in compatible Carrier HVAC equipment. As a genuine Carrier replacement part, this TXV ensures a factory-correct fit and reliable operation, minimizing the risk of refrigerant overfeeding or underfeeding that can lead to compressor damage or reduced system efficiency.
What Is a TXV?
A thermostatic expansion valve (TXV) is a critical refrigeration component that regulates the flow of refrigerant into the evaporator coil based on superheat conditions. By maintaining the correct refrigerant charge at the evaporator inlet, the TXV maximizes heat transfer efficiency, protects the compressor from liquid slugging, and helps the system achieve its rated capacity.
Key Features
- Genuine Carrier OEM replacement TXV valve
- Engineered for precise superheat control and refrigerant metering
- Factory-correct fit for compatible Carrier systems — no modification required
- Helps maintain rated system capacity and energy efficiency
- Protects the compressor by preventing liquid refrigerant slugging
