Description
The Bard HVAC 5651-212BX Expansion Valve is a thermostatic metering tool that regulates the flow of liquid refrigerant entering the evaporator coil based on cooling demand. It responds to pressure and temperature variations within the system to maintain proper superheat and stable coil operation. In HVAC systems, it is used in Bard packaged and wall-mounted units to ensure accurate distribution within the cooling circuit, supporting efficient heat exchange and steady performance during varying load conditions. It is used in commercial and institutional air conditioning equipment where precise flow control is required for dependable and consistent operation.
