Description
The Bard HVAC 5651-200BX Expansion Valve 3/8″ x 3/8″ is a thermostatic metering part that regulates flow into the evaporator coil based on cooling demand. It adjusts the entry of liquid refrigerant in response to temperature and pressure variations, ensuring proper superheat control and stable coil operation. In HVAC systems, it applies in packaged units to support balanced distribution within the cooling circuit and maintain efficient heat transfer during operation cycles. It is commonly applied in wall-mounted and sealed equipment where precise flow regulation is required for consistent system performance and compressor protection.
