Carrier EA36UZ133 R-410A Thermostatic Expansion Valve 7/8" x 1-3/8" TXV

The Carrier EA36UZ133 is an OEM thermostatic expansion valve (TXV) engineered for use in commercial R-410A (Puron) refrigerant systems. Designed with 7/8" liquid line and 1-3/8" suction line connections, this valve is built for large-capacity HVAC equipment including rooftop units, air handlers, and commercial split systems.

The thermostatic expansion valve plays a critical role in system efficiency by precisely metering refrigerant flow into the evaporator coil. It continuously monitors suction line temperature and pressure, automatically modulating flow to maintain the correct superheat level — protecting the compressor and maximizing system performance.

Key Features:

• OEM Carrier replacement part — direct factory fit
