Description
The Carrier EA36UZ134 is an OEM thermostatic expansion valve (TXV) engineered specifically for use with R410a refrigerant in Carrier HVAC systems. Designed to deliver precise refrigerant metering, this TXV regulates the flow of refrigerant into the evaporator coil, maintaining optimal superheat levels and maximizing system efficiency and performance.
Key Features
- OEM Carrier replacement TXV for accurate, reliable fit and function
- Compatible with R410a refrigerant — the industry-standard, environmentally preferred refrigerant
- Precisely meters refrigerant flow to the evaporator for optimal superheat control
- Helps maintain peak system efficiency and protects the compressor from liquid slugging
- Built to Carrier’s exacting quality standards for long service life
- Direct OEM replacement — no modifications required for compatible Carrier equipment
Why Use an OEM TXV?
Using a genuine Carrier TXV ensures your system operates within designed parameters. A properly functioning thermostatic expansion valve is critical to system efficiency, comfort delivery, and compressor longevity. Aftermarket substitutes may not provide the precise flow characteristics required by Carrier equipment, potentially leading to reduced efficiency or premature component failure.
Application
- Designed for use in compatible Carrier residential and light commercial HVAC systems
- Suitable for R410a refrigerant circuits
- Consult your equipment documentation or a qualified HVAC technician to confirm compatibility with your specific Carrier unit
Installation Notes
Installation should be performed by a licensed HVAC technician. Always recover refrigerant in accordance with EPA Section 608 regulations before servicing refrigerant circuits. Verify system compatibility using the Carrier model and serial number prior to installation.
