Electric actuator selection needs to know2018-01-12I. Determine the output torque of the electric actuator according to the torque required by the valve
The torque required to open and close the valve determines the output torque of the electric actuator, which is generally proposed by the user or selected by the valve manufacturer. As the actuator manufacturer, it is only responsible for the output torque of the actuator, which is required for the normal opening and closing of the valve. The torque is determined by the valve diameter, working pressure and other factors, but due to the difference in the processing accuracy and assembly process of valve manufacturers, the torque required for valves of the same specification produced by different manufacturers is also different, even if the same valve manufacturer produces the same torque. The torque of the valve is also different. When the torque of the actuator is too small, it will cause the valve to be unable to open and close normally. Therefore, the electric actuator must choose a reasonable torque range.
