Seeking advice on the selection of electric actuators
Thread Content
As the title suggests, when choosing an electric actuator for gate valves/stop valves, should the decision be based on torque or on thrust? It seems to me that if torque is used as the criterion, then gate valves with larger diameters will require very high levels of torque, which makes it difficult to choose an appropriate actuator. On the other hand, using thrust as a criterion seems easier. Moreover, many manufacturers provide parameters for the actuators of gate valves/stop valves, but in many cases only thrust is specified, such as in the case of bevel gears. However, customers generally request torque to be provided. Let’s all share our opinions. Thank you
Gate valves and globe valves generally use multi-turn actuators; for rotary types, it is of course necessary to consider torque
Torque must be available in order to select an electric actuator； Otherwise, if there’s a problem with the selected electric head, it will be troublesome.
