We know that the torque required for the valve to open and close determines the output torque of the small torque electric valve actuator. It is usually recommended by the user or the valve manufacturer can choose it. As a small electric valve actuator manufacturer, it is only responsible for the output torque of the actuator. The torque required for the normal opening and closing of the valve is determined by factors such as the size of the valve and the working pressure, but the machining accuracy and assembly process of the valve manufacturer are different.
Small torque electric valve actuator have a wide range of applications
Therefore, the torque required for different specifications of the valve produced by different manufacturers is also different. Even the torque of the same specification valve produced by the same valve manufacturer is different. When the torque selection of the actuator is too small, the valve cannot be normally opened and closed. Therefore, the small electric valve actuator must choose a reasonable range of torque.
Determine electrical parameters based on selected electric valve actuator
Because the electrical parameters of different actuator manufacturers are different, it is generally necessary to determine the electrical parameters when designing the selection, mainly motor power, rated current, secondary control loop voltage, etc., often negligence in this respect, the result control system Mismatch with the parameters of the small electric valve actuator causes malfunctions such as working time open tripping, fuse blowing, thermal overload relay protection and jumping.
