BASO H15DA-3 Valve

The BASO H15DA-3 Valve is a 3/4" NPT automatic shut-off pilot gas valve designed for reliable regulation in heating applications utilizing natural gas or liquid propane. Engineered to handle pressures up to 0.5 PSI, this powerhouse component features a 1/8"-27 NPT pilot tap located over the inlet to streamline pilot gas flow without the need for a Rotor "B" valve. This specific model serves as a drop-in direct replacement for H15DA-1, H15DA-3C, and H15CA-1 units, making it an essential stock item for field technicians maintaining older commercial or industrial boiler systems. By consolidating multiple older H15 series configurations, the H15DA-3 simplifies inventory while ensuring high-capacity performance. Its robust internal construction is optimized for thermocouple-driven safety circuits, providing a fail-safe shutdown if the pilot flame is extinguished, thereby preventing hazardous gas accumulation in the combustion chamber.

• Universal Compatibility: Efficiently replaces legacy models including H15DA-1 and H15CA-1 without requiring manifold modifications.
• Multi-Fuel Rated: Certified for use with both Natural Gas and LP Gas applications up to 0.5 PSI.
• Streamlined Installation: Features an internal pilot gas flow design that eliminates the requirement for external "B" valves.
• Precision Ports: Includes a 1/8"-27 NPT pilot tap positioned over the inlet for straightforward tubing connections.

Common Questions

Can the BASO H15DA-3 be used in high-pressure systems?
No, this valve is specifically rated for low-pressure applications not exceeding 0.5 PSI. Using this valve in high-pressure environments can lead to diaphragm failure or unsafe operating conditions.

Is this valve compatible with mercury-style flame sensors?
The H15DA-3 is engineered for use with standard thermocouples. If you are retrofitting a system, ensure your power unit requirements match the millivolt output of your current thermocouple setup.

Does this unit include a pressure tap for clocking the meter?
This specific model is a "No Pressure Tap" version. For setups requiring downstream pressure monitoring, an external tap must be utilized in the piping manifold.
