• Expansion Valve - Service

The Bard Manufacturing S5651-102 expansion valve (TXV valve) is an OEM refrigerant metering component used in Bard wall-mount air conditioning equipment to regulate refrigerant flow into the evaporator coil, helping the system maintain proper superheat and stable cooling performance. When a TXV sticks, leaks, or loses control, you can see issues like poor capacity, coil icing, or erratic pressures, and replacing it with the correct Bard service valve helps restore the unit to factory operating intent. This part is commonly referenced as a 3/8 in x 3/8 in thermostatic expansion valve in Bard parts listings, so verify your model and serial-specific parts list before ordering to confirm the exact application and connections for your unit.
