Description
The ClimateMaster 33B0043N04 thermostatic expansion valve assembly used to regulate refrigerant flow into the evaporator section of compatible HVAC systems. It features 3/8 inch ODF inlet and outlet connections for brazed installation, supports a 2-ton capacity, includes a 15-blade sensing element configuration, and uses a 30-inch capillary tube for temperature response feedback. The assembly meters refrigerant based on system load conditions to maintain proper superheat and stable evaporation. In HVAC systems it is fitted in the liquid line upstream of the evaporator, supporting balanced cooling performance and controlled refrigerant distribution across the cycle.
