Selection of electric actuators for electric butterfly valves
2023.01.16
Due to the combination of butterfly valves and electric devices, the correct selection of electric devices after determining the butterfly valve is an important factor related to whether it can meet engineering needs in practical use. When selecting an electric device, not only should the aforementioned working environment, electrical control, and general technical performance be considered, but also the comprehensive technical performance of the electric device should be comprehensively considered.

The brake of the hoist is one of the important components, and each independent driving mechanism must have its own brake set. In the lifting mechanism, the brake is used to adjust the descending speed of the heavy object, brake and hold the heavy object, so that it can reliably hang in the air; In the walking mechanism, the brake is used to absorb the inertia in motion, causing it to stop walking within a certain braking distance.
