Description
The Bosch HVAC 8733953235 Thermal Expansion Valve (TXV) is a refrigerant calibration meter used to regulate flow into the evaporator based on cooling demand and system load conditions. It operates through a thermostatic sensing bulb and diaphragm mechanism that continuously adjusts the valve opening in response to temperature and pressure changes, maintaining proper superheat for stable vaporization and compressor protection. In HVAC systems used in residential and commercial air conditioning and heat pump applications, it is positioned in the liquid line before the evaporator coil to ensure controlled expansion and efficient heat exchange.
