BASO H19AL-2 Gas Valve

The BASO H19AL-2 Automatic Shut-Off Pilot Gas Valve is a critical safety component designed for Natural Gas and Liquid Propane (LP) applications requiring a dependable 100% shut-off mechanism. This 3/8" NPT inlet and outlet gas valve is rated for pressures up to 0.5 PSI (14" W.C.), making it a standard choice for commercial cooking equipment and space heating units. Featuring a 1/4" compression pilot tap located on the left side and an integrated pilot adjustment screw, the H19AL-2 allows for precise flame calibration in the field. This unit is electronically and mechanically identical to the H19AL-2C, ensuring seamless HVACR part replacement cross-compatibility. Built for high-ambient environments, the BASO pilot valve utilizes a robust internal power unit that reacts instantly to a loss of thermocouple voltage, preventing unburned gas from accumulating. This valve is a direct solution for contractors maintaining gas commercial ovens and industrial fryers where automatic gas shut-off reliability is non-negotiable.

Key Benefits

• Universal Fuel Compatibility: Factory-ready for both Natural Gas and Propane systems without needing conversion kits.
• 100% Safety Shut-off: Provides a complete gas block to both the main burner and the pilot if the flame is extinguished.
• Compact 3/8" NPT Hub: Standardized threading ensures straightforward installation in tight HVACR equipment cabinets.
• Built-in Pilot Adjustment: Allows technicians to fine-tune the pilot flame to ensure optimal thermocouple millivolt output.
• Interchangeable Design: Fully replaces the H19AL-2C model with no modifications to piping or mounting required.

Common Questions

What is the maximum pressure rating for the H19AL-2?
This valve is designed for low-pressure systems and is rated for a maximum of 0.5 PSI. Exceeding this pressure can damage the internal diaphragm and power unit.

Where is the pilot tap located on this model?
The BASO H19AL-2 features a 1/4" compression coupling pilot tap located on the left side of the valve body when looking at the inlet.

Can this valve be used with a 750mv thermopile system?
No, the H19AL-2 is engineered specifically for use with a standard 30mV thermocouple. Ensure your pilot assembly matches these electrical requirements for proper operation.
