BASO H43GA-3 Gas Valve

The BASO H43GA-3 Gas Valve is an industrial-grade automatic shut-off pilot gas valve engineered for precision control in high-demand heating applications. This 1/2" NPT valve is rated for pressures up to 0.5 PSI and is fully compatible with natural gas and LP gas systems. Designed specifically for tight-access installations, the H43GA-3 features a 1/4" square rod instead of a standard handle, making it the preferred floor furnace gas valve for contractors. The unit includes a 1/4" compression pilot tap located on the right side, ensuring the pilot receives the same gas flow rate as the main burner. This model is 100% identical to the H43GA-3C, providing a direct replacement for pilot-out only safety systems. With robust construction and a manual shut-off feature, it ensures reliable service in wall heaters and space heating equipment without the need for complex pilot adjustments.

Key Benefits for Technicians

• Broad Compatibility: Seamlessly handles both Natural Gas and Liquid Propane (LP) conversions.
• Specialized Control: The 1/4" square rod design allows for remote operation in floor furnace applications.
• High Flow Efficiency: Pilot tap configuration maintains gas flow parity with the main valve for consistent ignition.
• Simplified Installation: Features 1/2" NPT inlet/outlet ports and a no-adjustment pilot design for rapid field replacement.
• Proven Safety: Integrated automatic shut-off pilot valve mechanism prevents gas accumulation during flame failure.

Common Questions

Is the BASO H43GA-3 compatible with my older floor furnace?
Yes, if your system utilizes a 1/4" square rod for manual control and requires a 1/2" NPT connection, this valve is the standard replacement for most gravity-fed floor furnaces.

Can I adjust the pilot flame on this model?
No, the H43GA-3 is a pilot-out only design with no pilot adjustment. It provides a fixed flow to ensure the safety of the thermocouple or thermopile circuit.

Does this valve replace the H43GA-3C?
Yes, the BASO H43GA-3 and H43GA-3C are technically identical and can be used interchangeably in all HVAC and heating applications.
