Carrier EA36YP289 Valve Assembly

When you are dealing with a 4-ton cooling application, precise refrigerant metering is non-negotiable for system efficiency. The Carrier EA36YP289 Valve Assembly is a high-performance thermostatic expansion valve (TXV) designed to maintain the exact superheat required by the evaporator coil under varying thermal loads. This bi-metal expansion valve utilizes a specialized metering device to modulate liquid refrigerant flow, preventing liquid slugging and protecting the compressor from premature wear. As a technician, you know that performance hinges on compatibility; the EA36YP289 is the direct replacement for EA36YD149, making it the essential OE replacement part for Carrier, Bryant, and Payne residential split systems and heat pumps. Optimized for R-410A refrigerant, this assembly ensures consistent subcooling and pressure drops, keeping the 4-ton HVAC capacity within factory design parameters even as outdoor ambient temperatures shift. Its robust bi-metal construction provides the thermal stability needed for long-service reliability in professional HVAC mechanical services.

• Direct OEM Compatibility: Engineered as a drop-in replacement for the discontinued EA36YD149, ensuring identical fit and port alignment.
• Enhanced Evaporator Protection: Prevents compressor flooding by providing precise control over the refrigerant mass flow rate.
• Superior Thermal Response: The bi-metal composition offers rapid adjustment to load changes, maximizing EER and SEER ratings.
• R-410A Optimized: Designed specifically for high-pressure R-410A systems with a 4-ton capacity rating.

• Is this compatible with the EA36YD149? Yes, the EA36YP289 is the official manufacturer-designated substitute for the EA36YD149 model.
• What tonnage is this valve rated for? This is a dedicated 4-ton TXV assembly tailored for large-capacity residential evaporators.
• Does this include the external equalizer line? This assembly is designed to match the factory specifications for the supported Carrier and Bryant coil models.
