Worm gear flange butterfly valve

Overview：

Worm gear flange butterfly valve refers to a butterfly valve that adopts a worm gear transmission device and a flange connection structure. It achieves manual or auxiliary power drive through the deceleration and torque increasing characteristics of the worm gear, combining the installation stability of flange connection with the labor-saving and precise control advantages of worm gear transmission. Its core function is to cut off, adjust or reverse the fluid through the rotation of the butterfly plate (0 °~90 °), which is suitable for working conditions that require a large opening and closing torque but do not require automatic control.
