VBGXH Groove Signal Worm Gear Butterfly Valve

Product Overview

The VBGXH Groove Signal Worm Gear Butterfly Valve utilizes a worm gear drive mechanism. As the cam rotates, it presses or releases the contact of the signal device at predetermined positions, correspondingly outputting an "on/off" electrical signal to indicate the open or closed status of the butterfly valve. It offers advantages such as easy installation, material savings, quick operation, and space efficiency, making it widely suitable for water supply and drainage systems, as well as fire protection systems in municipal, civil, and industrial applications.
