Torque overload protection
Valve electric device is used to operate the valve and was one of the valves connected to the device. The device is driven by electricity, their motion process can be stroke, torque, or to control the size of the axial thrust. As the valve should be the work of electrical device characteristics and utilization depend on the type of valves, fittings and valves regulate the work of the pipeline or equipment location. Therefore, control valve electric device the right choice; consider the prevention of overload (working torque higher than the control torque) has become essential to the occurrence of a ring.
Valve electric device right choice should be based on: 1. Operation torque: Operation torque is to select the main valve electrical device parameters. The output torque electric actuator valve operation should be the greatest moment of ~ times. 2. Operation Thrust: the host structure ofMOTORIZED VALVE ACTUATOR the valve electric device, there are two, one is not configured thrust plate, this time directly to the output torque; the other is equipped with thrust plate, and this time the output torque of the valve stem through the thrust disk nut is converted to the output thrust. 3. Number of output shaft rotation circle:
