Multi-turn electric actuators
Multi-turn electric actuators output torque and withstand bi-directional thrust by the thrust component, so they are often used for gate, stop valves, as well as similar ones to drive the valve opening and closing and control the opening degree of valves. As another kind of typical applications, combining multi-turn electric actuators with worm gearboxes can be used on part-turn applications, such as butterfly and ball valves.

Part-turn electric actuators
Part-turn electric actuators are mainly used for butterfly, ball valves, as well as similar ones to drive the valve opening and closing and control the opening degree of valves. The individual part-turn actuators are designed with compact structure and shape and their output torque range is small compared to the combination products (combinations of multi-turn electric actuators and worm gearboxes).

Multi-turn gearboxes output torque and withstand bi-directional thrust by the thrust component, so they can be used for gate, stop valves, as well as similar ones. As another kind of typical applications, the torque-only multi-turn gearboxes can be used as the intermediate reduction gearboxes of the combinations. The combination of multi-turn gearbox and multi-turn electric actuator generates large output torque or flexible output speed. A handwheel can be supplied for manual operation.
Part-turn gearboxes are mainly used for butterfly, ball valves, as well as similar ones. Part-turn gearboxes combined with multi-turn electric actuators act as part-turn electric actuators. A handwheel can be supplied for manual operation.br />
The controls & control cabinets are electrical equipments which need to be used with electric actuators. For being equipped with a large variety of control and protection functions, they can either remote operate the valve or realize the automatic control by receiving the upper PC signal. The controls & control cabinets with varies installation and protection forms can be flexibly installed in indoor, outdoor and explosion-proof environment.
The control modules can realize some special control or protection requirements when they are installed in the electric actuators as relatively independent electronic products.
