Grooved Butterfly Valve:

The grooved butterfly valve is operated by a worm gear and worm drive. As the cam rotates, it presses down or releases the contacts on the signal device at predetermined positions, correspondingly outputting "on" or "off" electrical signals to indicate the valve's open or closed status. Grooved butterfly valves are classified into two types: handle-operated grooved butterfly valves and worm gear-operated grooved butterfly valves.

 Features of Grooved Butterfly Valve:

 Compact Structure: The grooved butterfly valve features a compact structure, small size, lightweight, flexible operation, and convenient maintenance.

Reliable Sealing: It provides reliable sealing performance, unaffected by medium injection (bi-directional sealing).

Large Flow Area: It offers a large flow area with low flow resistance and high flow capacity.

Durable Construction: The valve disc is fully coated with rubber, providing resistance to aging, radiation, and ensuring durability.
