BASO H15DA-4 Gas Valve

The BASO H15DA-4 is a robust, manual-reset automatic shut-off pilot gas valve designed for high-demand reliability in commercial and industrial combustion systems. This 3/4" NPT valve is rated for both natural gas and liquid propane applications up to a maximum inlet pressure of 0.5 PSI. Engineered for drop-in compatibility, the H15DA-4 is identical to H15DA-4C, ensuring seamless integration into existing manifolds. The unit features internal pilot gas flow without a Rotor B valve, simplifying the setup for thermocouple-operated safety shut-off systems. Technical technicians will appreciate the versatile porting, which includes a 1/8"-27 NPT pilot tap positioned over the inlet and dual 1/8"-27 NPT pressure taps on both the left and right sides for precise gas pressure testing and commissioning. This Baso Gas Products valve is a critical component for maintaining safety standards in pilot burner ignition sequences, providing a positive seal if the pilot flame is extinguished.

• Universal Fuel Compatibility: Fully rated for Natural Gas and LP Gas applications, reducing the need for multiple SKUs on the service truck.
• Precision Monitoring: Dual 1/8" NPT taps allow for accurate upstream and downstream pressure readings during high-stakes diagnostics.
• Compact Manifold Integration: The 3/4" female NPT inlet and outlet provide high flow capacity while maintaining a standard footprint for HVAC gas valve replacement.
• Reliable Safety Interface: Interlocks directly with a standard thermocouple to provide immediate 100% shut-off upon loss of pilot flame.

Is the BASO H15DA-4 interchangeable with the H15DA-4C model?
Yes, these models are technically identical in form, fit, and function for your pilot safety valve requirements.

What is the maximum pressure rating for this valve?
The valve is designed for low-pressure systems with a maximum rating of 0.5 PSI (14 inches water column).

Does this unit support internal pilot flow?
Yes, this model features internal pilot gas flow and does not utilize a Rotor "B" valve configuration.
