It features a self-locking function and a manual reset option in emergencies. When the coil is energized, the plunger loses support, allowing the spring to close the valve quickly and lock it in place. Once powered off, the valve remains closed until manually reset by pulling the plunger back up. This valve is ideal for industrial gas applications where reliability, safety, and ease of use are essential. Its robust construction and advanced design make it a preferred choice in various gas control systems.
