BASO H91BA-3C REVB Gas Valve

The BASO H91BA-3C REVB Gas Valve is a 120V 1/4" NPT electrically operated shutoff valve engineered for precision fuel management in high-demand heating systems. As a veteran-grade HVAC gas safety valve, the H91 Series is designed to automatically regulate flow based on demand signals from thermostats or controllers, supporting a maximum inlet pressure of 0.5 psi. This direct replacement for H91BA-3 incorporates a Revision B modification specifically for the electrical connector, ensuring improved reliability for localized furnace repair and boiler maintenance. With a 100,000 BTU/hr capacity and 30-inch leads, this automatic gas shutoff valve is compatible with natural gas and LP gas applications, including commercial cooking equipment, wall furnaces, and water heaters. Contractors trust its rugged aluminum body and wide ambient temperature range—from -40°F to 175°F (CSA)—for long-term service in rigorous industrial and residential environments.

• Universal Compatibility: Seamlessly manages both natural gas and liquid propane (LP) at pressures up to 0.5 psi.
• Optimized BTU Capacity: Rated for 100,000 BTU/hr to support standard heaters and commercial kitchen appliances.
• Engineered Durability: Features an aluminum valve body designed to withstand high surface temperatures in commercial boiler rooms.
• Streamlined Installation: Equipped with 30-inch leads and a standard 1/4" x 1/4" NPT connection for fast field replacement.
• Direct OEM Logic: Updated Revision B electrical connection provides a secure interface for modern 120V control circuits.

Is the H91BA-3C REVB compatible with my older H91BA-3 unit?
Yes, this is the direct replacement. The Rev B model features an updated electrical connection but maintains identical mechanical specs and 120V operating requirements.

Can I use this valve for low-pressure LP applications?
Absolutely. The BASO H91 Series is certified for use with LP gas and LP gas-air mixtures, provided the inlet pressure does not exceed 0.5 psi.

Does this valve come with the leads pre-attached?
Yes, the H91BA-3C REVB includes 30-inch leads as standard, reducing the need for additional wiring harnesses during installation.
