How Does The Working Principle of A Ball Valve Achieve Rapid Cutoff And Fluid Control?

Another important characteristic of a ball valve is its low operating torque. Due to the spherical design of the valve core, the resistance generated by the fluid when passing through the valve core is relatively small, so the operating torque is also relatively low. This means that a ball valve can be operated with a smaller handle or actuator, making the operation process more effortless and quick. Low operating torque not only improves the convenience of operation but also reduces the wear on the valve core and sealing seat during the operation process, prolonging the service life of the valve.

The channel design of the ball valve enables it to adjust the fluid flow by partially opening. When the valve core is rotated to a position between fully open and fully closed, the fluid will be restricted to a certain extent when passing through the channel of the valve core, thereby realizing the adjustment of flow. Although this adjustment method is not as accurate as that of a throttle valve or a globe valve, it is still very effective in some occasions where rapid flow adjustment is required.
