5651-138 OBSOLETE
- Expansion Valve 3/8 X 3/8
Bard part number 5651-138 is an OEM thermostatic expansion valve (TXV) with 3/8 inch x 3/8 inch connections used in Bard wall-mounted air conditioners and related HVAC equipment to meter refrigerant into the evaporator coil at the correct rate. A properly operating TXV helps maintain stable suction conditions and coil performance, which supports consistent cooling and protects the compressor from poor refrigerant control symptoms like flooding or starving. This replacement is intended to match Bard factory fit and function, making it a solid choice when you are correcting improper superheat, replacing a restricted valve, or completing a sealed system repair where the metering device is suspected or confirmed faulty.
