Electric actuated butterfly valves are mainly used in power plants and nuclear power plants because in high pressure water systems which require a smooth, stable and slow process. The main advantage of an electric actuated butterfly valve is the high stability and constant thrust applied by the user. The anti-deviation ability of the electric actuator is very good, the output torque is basically constant, can be a good way to overcome the imbalance of the media to achieve accurate control of the process parameters, so the control accuracy is better than pneumatic actuator.
