BASO H91AA-4C REVB Gas Valve

The BASO H91AA-4C REVB is a heavy-duty automatic gas shut-off valve engineered for intermittent pilot ignition and standing pilot systems. Operating at 120V AC, this solenoid-actuated valve provides precise fuel control with a capacity of 70,000 BTU/hr. Featuring a 1/8" NPT inlet and outlet, it is designed for integration into commercial cooking equipment, industrial heaters, and boilers where compact gas flow regulation is required. As the direct replacement for H91AA-4, the REVB model ensures seamless mechanical fitment and electrical compatibility for field repairs. This BASO gas valve is rated for natural gas and LP applications, utilizing a robust internal seat and spring assembly to maintain a bubble-tight seal under pressure. Technicians should verify electrical lead connections and pressure drop specifications during installation to ensure optimal performance in high-cycle environments. Its rugged construction minimizes downtime in demanding thermal processing applications.

Key Benefits

• High Thermal Capacity: Rated for systems up to 70,000 BTU, providing reliable flow for commercial HVACR equipment.
• NPT Threading: Standard 1/8" NPT connection allows for secure, leak-free integration with existing manifold piping.
• Compact Footprint: Designed for tight equipment cabinets where space for gas safety controls is limited.

Common Questions

What is the difference between the H91AA-4 and the H91AA-4C REVB?
The H91AA-4C REVB is the current production standard, offering improved internal components while maintaining the exact physical dimensions and electrical requirements of the legacy BASO H series valves.

Can this valve be used with Propane (LP)?
Yes, the BASO H91AA-4C is compatible with natural gas and liquefied petroleum, provided the system pressure is regulated within the valve's specified operating range.

Is the 120V coil replaceable?
This unit is typically serviced as a complete solenoid valve assembly to ensure the integrity of the pressure seal and automatic shut-off mechanism.
