Multi-turn electric valve actuators are suitable for gate valves, globe valves, diaphragm valves etc, which are required to turn 360°. These actuators are featured by compact structure, small volume, beautiful appearance, stable performance, high efficiency, high reliability, high protection capability and so on. Both operation at site and remote controlling can be carried out. So they have been applied in petroleum and chemical industries, power plant, water treatment and paper-making industries.
