Carrier EA36YD057 TXV Valve

Looking for a precise Carrier EA36YD057 TXV Valve for an R-22 refrigerant system? This thermal expansion valve is the reliable solution for maintaining optimal superheat and maximizing evaporator efficiency in residential and commercial split systems. Specifically engineered for Carrier HVAC parts replacement, the EA36YD057 ensures accurate metering across varying load conditions, preventing compressor flooding and slugging. As a hard shut-off TXV, it eliminates bleed-through during the off-cycle, which is critical for systems requiring high-pressure differentials. When performing a change-out, ensure you also replace the liquid line filter drier to maintain system dehydration and prevent debris from fouling the small orifice. This OEM thermostatic expansion valve features a threaded nut fitting on the inlet and a sweat connection for the outlet, requiring professional brazing techniques with nitrogen flow to prevent internal oxidation. Professional installers know that the bulb placement at the 10 or 2 o'clock position on the suction line is vital for accurate temperature sensing and stable system operation.

• Optimized Superheat Control: Precisely regulates R-22 refrigerant flow to maintain high system performance and efficiency.
• Hard Shut-Off Design: Prevents pressure equalization during the off-cycle, making it compatible with specific Carrier air conditioning configurations including manufactured housing furnace coils.
• Robust OEM Construction: Designed for industrial and commercial durability, ensuring stable metering under high-pressure demands.
• Reliable Protection: Guards the compressor against liquid slugging by maintaining a consistent superheat at the evaporator outlet.

Is the EA36YD057 compatible with R-410A systems?
No, this specific model is calibrated for R-22 refrigerant pressures and flow characteristics. Using it with R-410A will lead to improper metering and potential system failure.

Does this valve require a hard start kit?
Because the EA36YD057 is a hard shut-off TXV, it does not allow pressures to equalize during the off-cycle. A start capacitor and relay (hard start kit) are typically required on single-phase units to overcome the pressure differential upon startup.

What is the proper orientation for the sensing bulb?
On horizontal suction lines, the bulb should be mounted at the 10 or 2 o’clock position (never at the bottom) to avoid oil interference and ensure accurate refrigerant temperature readings.
