A manual or semi-automated actuator for valves (such as butterfly valves, gate valves, ball valves, etc.), which achieves valve opening and closing and adjustment through worm gear transmission. Its core features are labor-saving operation, high torque output, and precise control, suitable for large-diameter or high-pressure difference valves.
A worm gear transmission mechanism with signal feedback device, typically used for remote operation and status monitoring of gate valves, globe valves, and other valves. It combines the mechanical transmission of the manual worm wheel head with electrical signals, providing real-time feedback on the valve's open/close position (such as fully open, fully closed, or intermediate position), facilitating integration with automated control systems.
