Understanding Electric Ball Valves: A Comprehensive Guide

When the electric motor of the electric ball valve is started, the output shaft of the motor drives the spool to rotate through the gear reducer, thus controlling the flow of fluid. When the motor output torque is transmitted to the spool, the spool starts to rotate. In the process of rotation, the spool’s ball shape matches the spherical hole of the valve body, which can be rotated to control the on-off of the fluid. When the spool is rotated to exactly coincide with the aperture of the valve body, the fluid can pass freely; when the spool is rotated to mismatch the aperture, the aperture is blocked and the fluid cannot pass.
