BASO H17AA-2 Gas Valve

The BASO H17AA-2 is a heavy-duty, 1/8-inch NPT automatic shut-off pilot gas valve designed for reliability in standing pilot applications. Engineered for both natural gas and liquid propane (LP), this valve provides a critical safety layer by interrupting gas flow to both the main burner and the pilot should the flame be extinguished. With a maximum pressure rating of 0.5 PSI and a standard temperature range, it integrates seamlessly into diverse commercial and industrial heating setups. The unit features a 1/8-27 NPT pilot tap positioned over the outlet, ensuring straightforward installation and precise pressure monitoring. As a non-electric safety valve, it is an essential component for technicians servicing atmospheric burners where robust mechanical fail-safes are required. This Baso gas valve replacement is built to maintain system integrity under continuous operation, offering high-performance flow control for standing pilot systems and HVAC safety shut-off requirements.

Key Technical Benefits

• Universal Fuel Compatibility: Certified for use with natural gas and LP gas systems.
• Enhanced Safety: Provides 100% shut-off of gas flow upon pilot flame failure.
• Compact Profile: 1/8" NPT inlet/outlet allows for installation in tight mechanical envelopes.
• Technician-Friendly Design: Integrated 1/8-27 NPT pilot tap simplifies troubleshooting and pressure checks.
• Field Reliability: Durable construction meant for the rigors of standing pilot applications.

Common Questions

Can the BASO H17AA-2 be used in high-pressure systems?
No, this valve is specifically rated for low-pressure applications up to 0.5 PSI. Attempting to use it in high-pressure lines can lead to component failure.

Is this valve compatible with thermocouple or thermopile leads?
The H17AA-2 typically utilizes a standard thermocouple to hold the internal solenoid open; ensure your probe millivoltage matches the valve requirements for proper operation.

Does it support both 1/4" and 1/8" pilot lines?
This specific model features 1/8" NPT ports. Technicians should use appropriate bushings or fittings if adapting to different line sizes, though native 1/8" is recommended for optimal flow.
