BASO H91MG-8C REVB Gas Valve

The BASO H91MG-8C REVB Gas Valve is a high-capacity, normally closed solenoid gas valve engineered for precision fuel control in commercial and industrial heating systems. Designed for 24V AC operation, this 1-inch NPT valve provides a reliable power-to-open flow path, handling up to 505,000 BTU/hr of natural gas or liquid propane. A critical update for field technicians, the REVB model serves as the direct H91MG-8 replacement gas valve, featuring modified electrical connections via 1/4-inch male spade terminals for improved wiring security. With a maximum inlet pressure rating of 1/2 PSI (14" W.C.), this valve is a standard component for large-scale boilers, rooftop units, and industrial burners. Its robust aluminum body and high-flow orifice ensure consistent performance in high-demand environments. If you are retrofitting older H91 series valves, this unit provides the exact mechanical footprint required for a clean drop-in installation without repiping.

Key Benefits for Contractors

• Direct Drop-In Replacement: Specifically engineered to replace the H91MG-8, ensuring mechanical compatibility and reducing labor time on service calls.
• High BTU Throughout: Rated for up to 505,000 BTU/hr, making it suitable for high-output commercial gas heating applications.
• Fail-Safe Operation: As a normally closed solenoid valve, it provides immediate gas shut-off upon loss of power for enhanced system safety.
• Standardized Threading: Features a 1-inch NPT inlet and outlet for secure, leak-free integration with heavy-duty gas manifolds.
• Industrial Build Quality: BASO Gas Products’ heavy-duty construction prevents coil burnout and ensures reliable cycling in demanding environments.

Common Questions

Is the H91MG-8C REVB compatible with LP Gas?
Yes, this valve is rated for both Natural Gas and Liquid Propane (LP) applications, provided the inlet pressure does not exceed 0.5 PSI.

How does the REVB model differ from the original H91MG-8?
The REVB designation indicates a modification to the electrical connection. While the mechanical flow rates and pipe sizes remain identical, the wiring terminals have been updated for better field reliability.

Can this valve be mounted in any orientation?
For optimal performance and to meet standard safety codes, it is recommended to mount the valve in an upright position with the solenoid pointing upward.
