BASO H43BA-2 Gas Valve

The BASO H43BA-2 is a robust 1/2" NPT manual reset gas valve designed for commercial and industrial applications requiring secondary safety shut-off. This automatic pilot valve is compatible with Natural Gas and Liquid Propane (LP) at pressures up to 0.5 PSI. The H43 series features an integrated manual shut-off valve, providing technicians with a reliable solution for isolating fuel flow during maintenance. This specific configuration includes a 1/4" compression coupling pilot tap located on the right side, oriented with an opposite gas flow relative to the main valve. Engineered for mechanical 100% shut-off, it ensures that if the pilot flame is extinguished, the thermocouple-driven power unit drops out, completely halting gas delivery to both the pilot and main burner. Its compact 1/2-inch inlet/outlet footprint makes it an ideal drop-in replacement for standard standing pilot systems where space and safety compliance are critical.

• Multi-Fuel Compatibility: Rated for both Natural Gas and LP applications without requiring extensive conversion kits.
• Dual-Function Design: Consolidates an automatic safety shut-off and a manual gas cock into a single, durable housing to reduce leak points.
• Reverse Flow Configuration: The specific opposite-flow pilot tap orientation facilitates easier pilot tubing routing in complex burner manifolds.
• High Cycle Reliability: Built with industrial-grade materials to withstand the thermal stresses of continuous HVACR equipment operation.
• Standardized Connections: Utilizes 1/2" NPT threading and a 1/4" CC pilot port for seamless integration with existing thermocouple-based safety circuits.

What is the maximum pressure rating for the H43BA-2?
The valve is rated for a maximum pressure of 0.5 PSI (14 inches water column), making it suitable for standard low-pressure gas manifolds.

Does this valve require an external power source?
No, the BASO H43BA-2 is a millivolt-actuated safety valve that operates using the electrical output generated by a standard thermocouple.

Can I install this on a system with a left-side pilot orientation?
This specific model features a right-side pilot tap with opposite gas flow; technicians should verify their manifold clearance and tubing reach before installation.
