The hand-operated flange ball valve with automatic reset device is a specially customized ball valve that uses the force of high-strength springs. After opening or closing the ball valve with a handle, the force of opening or closing is released under the force, and the ball valve can automatically reset to its original state (fully open or fully closed). The ball valve adopts an extended handle, which requires less torque for opening and closing to ensure emergency use. The valve can be made of stainless steel 304/316L or other materials, and can also be connected with flanges or threads, supporting various special customizations.
