Product Formation

This Worm Gear Grooved Signal Butterfly Valve is a fire protection-certified (3C-approved) manual control valve designed for automatic sprinkler systems, fire hydrant systems, and water supply/drainage pipelines. It features a grooved (clamp-type) connection for quick, leak-proof installation, paired with a durable ductile iron body (rubber-lined for enhanced sealing) and a pinless ductile iron disc for stable flow control.

Operated via a robust worm gear mechanism, the valve enables smooth manual adjustment of flow on/off status. Its integrated signal transmitter provides real-time switch feedback (compatible with DC24V/AC220V circuits) to monitoring systems, ensuring visibility of the valve’s operational state.
