BASO H17CB-3 Gas Valve

The BASO H17CB-3 is a high-temperature automatic shut-off pilot gas valve designed for demanding standing pilot applications. Built for durability in high-ambient environments, this valve is rated for natural gas and liquid propane (LP) systems with a maximum pressure of 0.5 PSI. It features a 3/8" NPT inlet and outlet connection, providing a standard fit for many commercial and residential heating units. A critical feature for field technicians is the 1/8"-27 NPT pilot tap located over the outlet, ensuring precise pilot gas flow control. This model is functionally identical to the BASO H17CB-3C, allowing for seamless interchangeability in the field. When troubleshooting gas valve pilot failure, the H17CB-3 offers a reliable safety shut-off mechanism that triggers if the pilot flame is extinguished, protecting the system from unburned gas accumulation. Its robust construction ensures reliable performance in HVAC replacement parts inventories.

• Dual Fuel Compatibility: Certified for use with both natural gas and LP gas systems.
• High Temperature Rating: Engineered to withstand higher ambient temperatures than standard safety valves.
• Compact 3/8" NPT Footprint: Simplifies installation in tight cabinet spaces common in older standing pilot furnaces and boilers.
• Integrated Pilot Tap: Features a 1/8"-27 NPT tap positioned over the outlet for efficient pilot line routing.
• Interchangeable Design: Direct replacement for the H17CB-3C, reducing stock complexity.

What is the maximum pressure rating for the H17CB-3?
This valve is rated for a maximum inlet pressure of 0.5 PSI (14 inches water column), which is standard for low-pressure gas manifolds.

Can I use this valve for an intermittent pilot ignition system?
No, the BASO H17CB-3 is specifically designed for standing pilot gas valve applications where a constant flame is present to keep the thermocouple energized.

Does this valve include the thermocouple?
The valve requires a standard 30mV thermocouple for operation, which is typically sold separately or salvaged from the existing assembly if it remains within millivolt specifications.
