BASO H19LA-1 Gas Valve

The BASO H19LA-1 is a High Pressure Automatic Shut-Off Pilot Gas Valve engineered for heavy-duty industrial and commercial applications utilizing Natural Gas or Liquid Propane (LP). Designed to handle inlet pressures up to 25 PSI, this valve features 3/8" NPT inlet and outlet connections and a dedicated 1/8"-27 NPT pilot tap located on the right side. The integrated flow interrupter ensures that gas cannot flow to the main burner during the pilot lighting sequence, preventing unsafe accumulation and providing precise 100% shut-off capability if the pilot flame is extinguished. Built for durability in high-demand environments, the H19LA-1 is a standard thermocouple-operated safety valve compatible with various BASO pilot burners. Contractors rely on this gas safety shut-off valve for its robust aluminum body construction and reliable performance in systems where high-pressure regulation is critical for operational safety.

Key Benefits

• High-Pressure Rating: Rated for up to 25 PSI, making it suitable for specialized high-pressure gas systems.
• Flow Interrupter Safety: Incorporates a safety mechanism that prevents main burner gas flow until the pilot signal is established.
• Universal Media Compatibility: Certified for use with both Natural Gas and LP Gas applications.
• Compact 3/8" NPT Porting: Standard sizing allows for straightforward integration into existing manifold configurations for HVACR equipment.
• 100% Shut-Off: Reliable automatic gas shut-off ensures zero gas flow to the burner upon pilot failure.

Common Questions

Can the BASO H19LA-1 be used in low-pressure residential furnaces?
While it can function, this valve is specifically engineered for high-pressure gas applications up to 25 PSI. For standard 0.5 PSI residential systems, a dedicated low-pressure valve is typically used.

Does this valve require a specific power source?
No, the H19LA-1 is a millivolt safety valve that operates using the electrical current generated by a standard thermocouple, requiring no external wiring.

What is the purpose of the right-hand pilot tap?
The 1/8"-27 NPT pilot tap on the right allows for convenient pilot line routing in cramped equipment housings, ensuring easier accessibility for gas valve troubleshooting and maintenance.
