BASO H19NA-4 Gas Valve

The BASO H19NA-4 Gas Valve is a rugged, high-pressure automatic shut-off pilot gas valve designed for demanding commercial and industrial environments. This H19 series gas valve is engineered to handle natural gas and LP gas at inlet pressures up to 25 PSI, making it a critical component for crop dryers, space heaters, and industrial process equipment. The unit features a 1/4" NPT inlet and outlet with a 1/8"-27 NPT pilot tap positioned on the right side. A key technical advantage is the integrated flow interrupter, which ensures gas only reaches the pilot during the lighting sequence, preventing unsafe gas accumulation. If the flame heating the thermocouple is extinguished, the BASO H19NA-4 provides a complete shutoff of all gas flow. For technicians performing replacements, the H19NA-4 is identical to H19NA-4C, ensuring direct drop-in compatibility for existing systems requiring a pilot safety valve.

Key Benefits for Contractors

• High-Pressure Tolerance: Rated for up to 25 PSI, providing reliable control in high-demand industrial gas applications.
• Integrated Flow Interrupter: Enhances safety by restricting gas flow exclusively to the pilot during the manual lighting process.
• Universal Fuel Compatibility: Internally designed to manage Propane (LP) and Natural Gas without requiring separate valve bodies.
• Durable Aluminum Construction: The aluminum valve body provides high corrosion resistance and thermal stability in harsh environments.
• Fail-Safe Operation: Utilizes a standard thermocouple connection to ensure immediate 100% shutoff upon pilot flame failure.

Common Questions

What is the difference between the H19NA-4 and the H19NA-4C?
Technically, they are the same valve. The "C" suffix typically denotes bulk packaging or slight variations in OEM labeling, but the flow characteristics, 1/4" NPT sizing, and 25 PSI rating are identical.

Can this valve be used for low-pressure residential furnaces?
While it can handle gas, this is specifically a high-pressure gas valve. It is optimized for systems like crop dryers and industrial heaters. Cross-reference your manifold pressure requirements before installation.

Where is the pilot tap located on this model?
The H19NA-4 features a 1/8"-27 NPT pilot tap located on the right side of the valve body for standard pilot line integration.
