Description
The BASO H43AA 12 valve is part of BASO’s H43 Series of automatic pilot safety valves, featuring a manual shut off handle for On / Off / Pilot positions. Designed for natural gas, liquefied petroleum (LP) or LP gas air mixture systems, it delivers reliable shutdown of both pilot and main burner if flame is lost — ensuring safe operation. Built with a compact design and 3/8″ NPT inlet/outlet, the H43AA 12 is ideal for room heaters, wall furnaces, commercial cooking equipment, and other space constrained installations.
Features:
- 100% Shut off for Pilot & Main Burner: In the event of pilot flame failure, this valve automatically shuts off gas supply to both pilot and main burner for enhanced safety.
- Safe Lighting Interlock: Before main burner gas flows, the valve ensures gas flows only to pilot during lighting — reducing risk during ignition.
- Manual Shut Off Handle: On/Off/Pilot positions allow the unit to be operated or tested without a thermostat, adding convenience and control.
- Compact 3/8″ NPT Connections: With a female 3/8″ NPT inlet and outlet, the H43AA 12 fits into many existing gas piping installations.
- Rated for Standard Pressure & Temperature: Supports inlet pressure up to 0.5 psi (≈ 35 mbar) and ambient surface temperatures from 32 °F to 175 °F for H43_A models, making it suitable for standard residential/light commercial use.
- Versatile Fuel Compatibility: Suitable for natural gas, LP, or LP gas/air mixtures — helpful for installations converting fuel types or servicing mixed fuel equipment.
