5651-137 OBSOLETE
- Expansion Valve 3/8 X 3/8
The Bard 5651-137 expansion valve (3/8 x 3/8 connections) is an OEM refrigerant metering component used in Bard wall-mounted HVAC equipment to regulate refrigerant flow into the evaporator coil so the system can maintain proper superheat and stable cooling performance. If your unit is icing up, starving, flooding, or showing inconsistent suction pressures, a sticking or restricted expansion valve is a common cause, and replacing it with the correct Bard part helps restore the designed capacity and reliability. Confirm your Bard model and serial number and verify the 3/8 x 3/8 line sizing before ordering, since correct valve selection is critical to system operation and refrigerant charge setup.
