Description
The Carrier EA36UZ034 4-Ton Thermostatic Expansion Valve is a refrigerant metering component that controls the flow of coolant into the evaporator to maintain proper superheat levels and ensure efficient heat absorption. It operates through a sensing bulb and internal diaphragm system that adjusts fluid delivery based on temperature and pressure variations, providing precise flow regulation during operation, and HVAC systems depend on this control to maintain stable cooling performance and protect the compressor from liquid air-vapor return. It is placed at the evaporator inlet line, it forms a key part of the recirculating circuit, supporting balanced system operation, consistent coil performance, and stable cooling efficiency.
