Partial rotary electric actuators，collectively referred to as Q series actuators, are driving equipment for valves to achieve opening, closing, adjustment and control. This series of actuators have the characteristics of ful-featured,reliable performance, advanced control svstem, small size, licht weight, convenient use and maintenance.
Q series actuator is suitable for butterfly valve, ball valve, plug valve, damper and other valves that make 90°rotation. The valve can be controlled remotely, collectively and automatically. lt is widely used in powermetallurgy, petroleum,chemical,pharmaceutical, sewage treatment, agricultural irigation and other industries.
The performance of this series of ordinary products conforms to the requirements of GB / T24923-2010 "Technical Conditions for Ordinary Valve Electric Devices"
