Description
The Bard HVAC 5651-206 Thermal Expansion Valve is a refrigerant metering part used in HVAC systems to regulate the flow of coolant into the evaporator coil. It operates by sensing temperature and pressure changes to maintain proper superheat ensuring efficient heat transfer, and protecting the compressor from liquid refrigerant return. This valve is commonly used in Bard wall-mounted and packaged units, where it stabilizes cooling performance under varying load conditions. It is used in residential, commercial, and light industrial applications where precise refrigerant control is required for stable and consistent system operation.
