BASO H91LA-1 Gas Valve

The BASO H91LA-1 is a robust 120Vac automatic gas valve engineered for high-capacity applications in commercial and industrial HVACR systems. This 3/4" NPT gas valve features a straight-through body design and is compatible with both natural gas and liquid propane (LP), supporting inlet pressures up to 0.5 PSI. Rated at 430,000 BTU/hr (natural gas), it provides reliable flow control for large-scale heating equipment. The unit includes 30-inch wire leads and a top-mounted conduit connection for streamlined field wiring. This model is technically identical to the H91LA-1C, ensuring full compatibility when replacing that specific variant. Built for longevity in demanding environments, the H91LA-1 utilizes a solenoid-actuated mechanism to provide on/off gas flow control. Contractors can rely on this BASO series for consistent performance and standard 3/4 inch NPT pipe sizing integration, making it a staple for preventative maintenance and emergency repairs.

Common Questions

Is the BASO H91LA-1 compatible with residential low-voltage systems?
No, this is a 120Vac gas valve. It requires a 120V power supply and is not compatible with standard 24V residential thermostats without a transformer or relay.

Can this valve be mounted in any orientation?
The H91 series should be mounted according to manufacturer specifications, typically with the solenoid in the upright position to ensure proper plunger operation and seating.

What is the difference between the H91LA-1 and the H91LA-1C?
These parts are functionally and physically identical; the "C" suffix often denotes bulk packaging or specific OEM distribution channels, but the technical specifications remain the same.
