Electric actuator purchase should pay attention to the problem description

Electric actuator purchase should pay attention to the problem:
1. The electric device manufacturer with different electrical parameters of the electric actuator according to the selected electrical parameters is different, so the design of the model selection is usually to determine its electrical parameters, main motor power, rated current, secondary voltage control circuit. Etc., often overlooked in this regard, the control system does not match with the electric actuator to make travel in time and space travel, fuse blown, thermal overload relay protection jump failure.
2. According to the output torque of the electric actuator required for the torque of the valve, the torque required to open and close the valve determines how the electric actuator of the output torque is selected, usually by the user or by the valve manufacturer as an actuator. The manufacturer is only responsible for the output torque of the actuator. The torque required to open and close the normal valve is determined by the valve diameter and working pressure. However, due to the machining accuracy and assembly process of the valve manufacturer, the same specification valve produced by different manufacturers The required torque is also different. Even if there is a valve manufacturer's production specification, the valve torque is different. If the torque selection of the selected type actuator is too small, the valve cannot be opened/closed normally. Therefore, the electric actuator must select a reasonable range of rotation. Moment.
