It features 3/8″ NPT inlet/outlet connections and supports natural gas, liquefied petroleum (LP) gas or LP gas/air mixtures.Built for applications that demand both safety and durability, the H43AB 4 model includes a manual shut off handle and is engineered to operate in ambient temperatures up to 250 °F (0 °C to 121 °C) for the “B” class versions.
Features:
- High temperature design: Rated ambient temperature up to ~250 °F for “B” models — ideal for industrial kitchen equipment, fryers, grills, and other high heat service applications.
- Compact 3/8″ NPT ports: Allows easy retrofit or replacement in systems with standard 3/8″ gas piping.
- Automatic pilot safety shut off: If the pilot flame is lost, the valve automatically cuts off gas to both the pilot and main burner, preventing unburned gas release.
- Manual shut off handle (On/Pilot/Off positions): Enables safe ignition and convenient servicing without reliance only on thermostats.
- Fuel versatility: Works with natural gas or LP gas and compatible for LP gas/air mixtures, making it suitable for a range of equipment types.
