BASO H43AB-4 Gas Valve

The BASO H43AB-4 Gas Valve is a 3/8" NPT automatic shut-off pilot valve designed specifically for demanding high-temperature environments. Rated for up to 0.5 PSI, this valve provides reliable gas flow control for both natural gas and LP gas applications. It features an integrated manual shut-off and a 1/4" compression coupling pilot tap positioned on the right side, ensuring the pilot gas flow matches the main valve capacity. This model is a direct 1:1 replacement for the BASO H43AB-4C, maintaining the exact mechanical footprint and performance specifications required for industrial and commercial furnace maintenance. Engineered for durability, the high temperature range gas valve provides essential safety by halting gas flow to the main burner and pilot if the flame is extinguished. Contractors rely on the H43AB-4 for its mechanical simplicity and 3/8" NPT gas valve standard threading, which facilitates straightforward field installations and retrofits in compact mechanical housings.

• Compatible with Natural Gas and Liquid Propane systems for maximum job site versatility.
• Features a right-side pilot tap with 1/4" compression coupling for efficient pilot line integration.
• Designed for high-temperature applications, ensuring thermal stability in tight furnace cabinets.
• Provides 100% automatic pilot shut-off safety functionality upon flame failure.
• Directly replaces the H43AB-4C without requiring additional piping modifications.

Is the BASO H43AB-4 compatible with both Propane and Natural Gas?
Yes, this valve is engineered to handle both Natural Gas and LP Gas up to a maximum pressure of 0.5 PSI.

What is the difference between the H43AB-4 and the H43AB-4C?
The H43AB-4 and the H43AB-4C are identical in form, fit, and function; the H43AB-4 can be used as a direct replacement for the C-suffix model.

Where is the pilot tap located on this model?
The pilot tap is a 1/4" compression coupling located on the right side of the valve body relative to the gas flow direction.
