Carrier EA66ZZ007 Thermostatic Expansion Valve TXV 1/2 in Inlet x 7/8 in Outlet

The Carrier EA66ZZ007 is a thermostatic expansion valve (TXV), also called a thermal expansion valve or TXV metering device, for Carrier air conditioning and heat pump systems. It meters liquid refrigerant into the evaporator coil based on the superheat at the coil outlet. This helps the system run efficiently across a range of outdoor temperatures and load conditions.

Key Features:

• Brand and part number: Carrier EA66ZZ007
• Part type: Thermostatic expansion valve (TXV)
• Inlet connection size: 1/2 in
• Outlet connection size: 7/8 in
• Function: Regulates refrigerant flow to the evaporator to help maintain consistent superheat

A properly working TXV helps with efficient cooling, good temperature control and protection of the compressor. Fixed-orifice and TXV metering devices are not interchangeable, so replace a TXV with a TXV.
