  • 9043-031 OBSOLETE

  • NAT. VALVE SX345NS

Bard part number 9043-031 is an OEM natural gas valve (SX345NS) used in Bard wall mounted gas/electric HVAC equipment to regulate and safely control natural gas flow to the burner based on the unit’s low voltage heat call. A weak or sticking valve can cause ignition issues, nuisance lockouts, or inconsistent heating, so replacing it with the correct Bard OEM valve helps restore proper start up and stable flame operation to factory specifications. Because gas valves are application specific by capacity, manifold pressure, and electrical control style, confirm the part number against your Bard model and serial information before ordering and have installation and setup performed by a qualified technician with proper leak testing and combustion checks.
