Hussmann 403867 Expansion Valve FBVE 0.5 C 49

The Hussmann 403867 Expansion Valve is a refrigeration metering component used in compatible cooling systems. The FBVE 0.5 C 49 parameters identifies correct calibration for system integration. It is placed within the refrigerant line between the condenser and evaporator sections of the unit. It regulates refrigerant flow based on system load conditions to maintain proper pressure balance. It controls entry of refrigerant into the evaporator, supports stable cooling cycle performance, and assists in maintaining consistent temperature regulation. It is replaced during service when refrigerant control becomes unstable or system efficiency declines.
