The Bard HVAC 5651-191BX Expansion Valve is an essential component in HVAC systems with a 3/8” x 3/8” connection. In this capacity, it controls the amount of refrigerant that enters the evaporator coil to the right level. This metering process results in enablement of the refrigerant to expand in order to take heat from the surrounding air and cool the room. Advantages associated with this valve include efficiency of the system as a result of regulation of temperature, energy conservation as well as the prevention of the compressor from being damaged. Its precise function makes it possible to achieve better performance and durability of HVAC systems.
