Description
The BASO H43AA 1 is part of the H43 series from BASO Gas Products — a high quality automatic shut off pilot gas valve designed for safe lighting and dependable operation in gas appliances. It features a compact design, a 3/8″ female NPT (FNPT) inlet and outlet, and is suitable for natural gas, LP (liquefied petroleum) gas, or LP gas air mixtures. This valve blends automatic safety shut off capability with a manual shut off handle, making it suitable for both new installations and replacement applications in furnaces, wall mounted heaters, commercial cooking equipment, and other gas fired appliances.
Features:
- Automatic pilot safety shut off: If the pilot flame goes out, the valve automatically shuts off both the pilot and the main burner gas, enhancing operational safety.
- Manual shut off handle with On / Off / Pilot positions: Allows easy lighting and maintenance control without relying solely on thermostat signals.
- Compact 3/8″ FNPT connection size: Suitable for installations in dimensionally restricted spaces, making it easier to retrofit older equipment.
- Rated for moderate inlet pressure (~0.5 psi) and supports standard ambient surface temperature range (32 °F to 175 °F for H43_A models) in many typical applications.
- Dual fuel compatibility: Works with natural gas, LP gas, and LP gas air mixtures — allowing versatile usage across different appliance types.
