BASO H15HQ-5 Gas Valve

The BASO H15HQ-5 is a heavy-duty, automatic shut-off pilot gas valve designed for high-reliability performance in commercial and industrial heating applications. This 3/8" NPT gas valve is engineered for use with both Natural Gas and Liquid Propane (LP), rated for pressures up to 0.5 PSI. A technical equivalent to the H15HQ-5C, this model features a 1/4" compression coupling pilot tap positioned to the left of the inlet. It utilizes an external pilot gas flow configuration without a Rotor "B" valve and provides no pressure tap, streamlining the manifold layout. Built for failsafe operation, the internal thermocouple-operated power unit ensures immediate gas flow interruption if the pilot flame is extinguished. Technicians prefer this unit for its robust construction and consistent millivolt drop performance in demanding environments where precise pilot safety control is non-negotiable.

Key Benefits

• Universal Compatibility: Validated for Natural Gas and LP Gas systems, offering flexibility across various HVACR equipment.
• Automatic Safety Shut-off: High-quality magnet head assembly ensures rapid closure upon loss of flame signal.
• Compact NPT Porting: Standard 3/8" NPT inlet/outlet allows for easy integration into existing burner manifolds.
• Direct Replacement: Fully interchangeable with the BASO H15HQ-5C, maintaining identical mounting and flow characteristics.

Common Questions

Can the H15HQ-5 handle high-pressure gas lines?
No, this valve is strictly rated for low-pressure applications up to 0.5 PSI. Using this on higher pressure lines will damage the internal diaphragm and power unit.

Does this valve require an external power source?
No, this is a millivolt safety valve that operates using the electrical current generated by a standard thermocouple when heated by the pilot flame.

What is the difference between the H15HQ-5 and the H15HQ-5C?
Technically, these units are identical in form, fit, and function; the "C" suffix typically denotes bulk packaging for OEMs, but the performance specs remain the same.
