Carrier 30RA502111 TXV Valve

The Carrier 30RA502111 TXV Valve is a 1-inch sweat connection thermostatic expansion valve engineered for precision refrigerant metering in Carrier 30RAP AquaSnap chillers and 30XA AquaForce units. Manufactured by Sporlan (Model EBSVE 20), this OEM replacement valve is critical for maintaining target superheat and preventing liquid slugging in the compressor. By modulating flow based on evaporator outlet temperature and pressure, the 30RA502111 ensures the indoor coil does not freeze while maximizing heat transfer efficiency during high-load periods. The bi-metal composition and external equalizer support stable performance in high-pressure R-410A systems. Using an OEM Carrier TXV is vital for contractors looking to restore factory-spec subcooling and avoid common issues like hunting or starving the evaporator. This replacement thermal expansion valve includes the necessary mounting hardware for a standard field installation in commercial HVACR applications.

• Precise superheat control via an external equalizer to optimize chiller performance.
• Direct OEM fit for 1" sweat connections, reducing field modification time during valve replacements.
• High-pressure compatibility specifically rated for use in modern R-410A refrigeration circuits.
• Durable bi-metal construction designed to withstand the thermal cycling typical of commercial chiller operation.
• Standardized Sporlan EBSVE 20 design, a trusted industry benchmark for reliable refrigerant metering.

Is the sensing bulb pre-charged?
Yes, the powerhead assembly contains a dedicated refrigerant charge meant to provide the opening force required to modulate the valve based on suction line temperature.

What was the original manufacturer part number?
This is the factory-authorized replacement for the 30RA502111 and the Sporlan EBSVE series often found in original 30RAP equipment builds.

Does this valve require an external equalizer line?
Yes, this model utilizes an external equalizer to compensate for pressure drops across the evaporator, ensuring accurate superheat measurement.
