Carrier EA36UZ074 TXV Thermostatic Expansion Valve

Description

The Carrier EA36UZ074 is an OEM thermostatic expansion valve (TXV) engineered to deliver precise refrigerant metering and optimal system efficiency in Carrier HVAC equipment. As a factory-authorized replacement part, it ensures a direct-fit installation that restores your system to original manufacturer specifications without the guesswork of aftermarket alternatives.

What Is a TXV?

A thermostatic expansion valve is a critical refrigeration component that regulates the flow of refrigerant into the evaporator coil. By responding to suction-line temperature and pressure, the TXV maintains the correct superheat level, protecting the compressor from liquid slugging while maximizing heat-transfer efficiency across the coil.

Key Features

• Genuine Carrier OEM replacement thermostatic expansion valve
• Designed for precise refrigerant flow control and superheat regulation
• Direct-fit replacement for compatible Carrier systems
• Helps restore original system efficiency and capacity
• Manufactured to Carrier quality and performance standards
• Supports reliable compressor protection by preventing liquid floodback

Why Choose an OEM TXV?

Using a genuine Carrier TXV ensures compatibility with your system’s refrigerant type, operating pressures, and capacity range. Aftermarket valves may not match the factory-calibrated superheat settings, potentially leading to reduced efficiency, premature compressor wear, or system faults. The EA36UZ074 is the correct, manufacturer-approved solution for supported Carrier equipment.

Application

• Intended for use in compatible Carrier residential and light commercial HVAC systems
• Suitable for evaporator coil refrigerant metering applications
• Consult Carrier equipment documentation to confirm compatibility with your specific model

Installation Notes

Installation should be performed by a licensed HVAC/R technician. Proper nitrogen brazing practices, system evacuation, and refrigerant charging procedures must be followed in accordance with local codes and manufacturer guidelines. Always verify the correct TXV orientation and bulb placement per the equipment service manual.
