Description
The Carrier P540-4152 1.5-2 Ton Thermal Expansion Valve is an essential part used to regulate the flow of liquid refrigerant into the evaporator coil in HVAC systems. It works by sensing temperature and pressure at the evaporator outlet and automatically adjusting the valve opening to maintain proper superheat levels for efficient heat exchange. It is used in air conditioning and heat pump systems that operate refrigerant. It’s flow control, improved energy efficiency, and reliable system protection, helping ensure stable cooling performance and compressor safety in systems.
