BASO H17DB-5 Pilot Valve

The BASO H17DB-5 is a heavy-duty, 1/2" NPT automatic shut-off pilot gas valve engineered for standing pilot systems in commercial and industrial applications. This pilot flow interrupter valve is designed to handle both natural gas and liquid propane (LP) at pressures up to 0.5 PSI. Built for high-ambient environments, its high-temperature construction ensures reliable performance in demanding mechanical rooms. The unit features a 1/8"-27 NPT pilot tap positioned over the outlet, facilitating precise line monitoring and installation versatility. As a direct replacement gas valve for the legacy H17DB-4 and H17DB-5C models, it maintains the exact form and fit required for rapid field service. This standing pilot safety valve utilizes a robust internal mechanism to ensure positive shut-off if the pilot flame is extinguished, preventing hazardous gas accumulation. Technicians can rely on this fail-safe gas control for heaters, boilers, and industrial ovens requiring a 1/2 inch gas connection.

Key Benefits

• Universal Compatibility: Rated for both Natural Gas and LP applications, reducing vehicle stock requirements.
• High-Temperature Resilience: Engineered to maintain structural integrity in high-heat zones near burners and heat exchangers.
• Mechanical Safety: Provides 100% shut-off of both pilot and main burner gas in the event of pilot outage.
• Seamless Retrofit: Replaces H17DB-4 and H17DB-5C without piping modifications.
• Integrated Monitoring: Features a dedicated 1/8" NPT tap for accurate pressure testing and pilot line integration.

Common Questions

What is the maximum pressure rating for the BASO H17DB-5?
This valve is designed for low-pressure systems and is rated for a maximum inlet pressure of 0.5 PSI (approximately 14 inches water column).

Which models does the H17DB-5 replace?
The H17DB-5 is the certified replacement for the discontinued BASO H17DB-4 and H17DB-5C models, sharing the same 1/2" NPT inlet/outlet specifications.

Can this valve be used with a 24V ignition system?
No, the H17DB-5 is a manual reset standing pilot valve that operates via a thermocouple/thermopile signal and is not an intermittent ignition solenoid valve.
