Description
The Carrier EA36UZ840 is an OEM thermostatic expansion valve (TXV) engineered for use in Carrier refrigeration and air conditioning systems. Designed as a direct replacement component, it ensures accurate refrigerant flow control to maintain optimal evaporator performance and system efficiency.
Product Overview
The thermostatic expansion valve is a critical component in the refrigerant circuit, metering the flow of liquid refrigerant into the evaporator coil. By responding to suction line temperature and pressure conditions, the TXV maintains the correct superheat level — protecting the compressor and maximizing heat transfer efficiency throughout the system.

- OEM Carrier replacement TXV for precise fit and performance
- Meters refrigerant flow to maintain proper evaporator superheat
- Helps protect the compressor from liquid slugging
- Supports consistent system efficiency and cooling capacity
- Designed for compatibility with Carrier equipment
- Durable construction for long-term reliability
Applications
- Carrier residential and light commercial air conditioning systems
- Direct replacement for failed or worn TXV components
- Refrigerant circuit service and maintenance applications
Why Choose the Carrier EA36UZ840 TXV?
Using a genuine Carrier TXV ensures your system operates as originally designed. An improperly sized or incompatible expansion valve can lead to reduced efficiency, compressor damage, or system failure. The EA36UZ840 provides the confidence of an OEM-spec component, making it the preferred choice for HVAC technicians performing reliable, long-lasting repairs.
