Carrier EA36YD090 TXV Valve

The Carrier EA36YD090 TXV Valve is a technical-grade thermal expansion valve engineered for precision refrigerant metering in high-efficiency residential and commercial air conditioning systems. As a genuine factory authorized part, this bi-metal constructed metering device is critical for maintaining the specific superheat required to optimize evaporator performance and protect the compressor from liquid slugging. The EA36YD090 is designed as a direct OEM replacement valve for a wide range of Carrier, Bryant, and Payne equipment, including 48VG, 50VG, and PA3G series package units. By accurately adjusting the refrigerant flow rate based on evaporator load, it prevents coil icing and ensures steady-state efficiency across varying ambient conditions. For service technicians, this valve offers a drop-in fit with standard ODF connections, facilitating faster repairs and restoring original equipment performance. Utilizing an HVAC expansion valve that meets exact factory specifications is necessary to maintain the operational integrity of R-410A and other compatible high-pressure systems.

• Precision Superheat Control: Maintains exact refrigerant flow to maximize heat transfer efficiency without risking compressor damage.
• Drop-in OEM Compatibility: Engineered specifically for Carrier-family equipment, ensuring correct mounting and port alignment.
• Durable Bi-Metal Construction: High-quality materials resist oxidation and thermal stress in demanding HVAC environments.
• System Reliability: Actively prevents evaporator coil icing and ensures consistent cooling cycles during peak demand.

What symptoms indicate the EA36YD090 needs replacement?
Technicians typically look for inconsistent superheat readings, frost patterns on the evaporator coil, or a compressor running at high discharge temperatures, suggesting a "hunting" valve or a restricted orifice.

Is the EA36YD090 compatible with R-410A systems?
Yes, this thermal expansion valve is designed to handle the pressure requirements and flow characteristics of R-410A systems commonly found in modern Carrier package units and split systems.

Does this valve come with the external sensing bulb?
Yes, as a complete thermal expansion valve assembly, it includes the integral sensing bulb required to monitor suction line temperature for real-time flow adjustment.
