Gearbox Operated Butterfly Valve - JUHAN VALVE

What is a Gearbox Operated Butterfly Valve?

A gearbox operated butterfly valve is a quarter-turn valve that uses a gear mechanism to assist in opening and closing the valve disc. This system enables reduced torque, smoother control, and easier operation, especially for large-diameter pipelines and industrial applications.
