Carrier 332368-750 Thermal Expansion Valve Kit

The Carrier 332368-750 Thermal Expansion Valve Kit is a genuine Factory Authorized Parts replacement engineered for high-precision refrigerant metering in R-22 HVAC systems. Designed specifically for 3 to 3.5 ton capacity units, this thermostatic expansion valve (TXV) maintains the necessary superheat to prevent liquid slugging while ensuring the evaporator remains fully active. As a direct replacement for EA36YD034, this bi-metal valve assembly features a 1/2" inlet connection with a hex nut fitting for secure integration into existing liquid lines. Since R-22 systems require exact pressure regulation to maintain efficiency, utilizing a factory-spec Carrier expansion valve is critical for field service and long-term system reliability. This kit provides the exact mechanical response needed to balance refrigerant flow through varying heat loads in residential or light commercial evaporator coils.
