Description
The ASCO H117AL122F1 is a 3-inch, 120 V AC normally closed high-flow hydramotor gas shutoff valve engineered for industrial and commercial combustion control systems. This valve combines a rugged cast-iron body with a dependable hydramotor electrohydraulic actuator to deliver safe, high-capacity gas control in demanding environments. An auxiliary switch provides remote status feedback, making it ideal for integration with automation and safety interlocks. The high-flow design supports large gas volumes, and the normally closed (N/C) configuration ensures the valve remains closed when de-energized, enhancing system safety.
