HVQ series
As a core product of Yangzhou Hengchun Electronics Co., Ltd., a professional China manufacturer of intelligent electric actuators, the HVQ Series Intelligent Electric Actuator perfectly integrates digital control with mechanical reliability design. Adopting high-efficiency gear transmission structure, this actuator is engineered for precise valve control in diverse industrial scenarios, featuring a standard output angle range of 0~90° with a 360° optional version. It boasts comprehensive self-diagnosis, humanized easy operation and long-term maintenance-free performance, making it a reliable intelligent control solution for building, pipeline, shipbuilding and multiple heavy industrial fields. As a key member of Hengchun’s electric actuators lineup, it is designed to adapt to harsh working environments and meet the high-standard control demands of industrial valves.
The dual design of digital control and mechanical stability ensures accurate signal transmission and stable mechanical operation, avoiding control errors caused by single-system faults and improving the overall safety of valve control systems.
Equipped with IP67 protection grade and C3 corrosion resistance, it can effectively resist high humidity, salt spray and dust, and withstand a wide operating temperature range of -25℃~+70℃.
Supports manual emergency operation in case of bus failure, ensuring uninterrupted valve control and continuous production/operation processes, which is a crucial safety guarantee for industrial on-site use.
The optimized gear transmission structure makes the actuator small in size and high in transmission efficiency, saving installation space and reducing energy consumption during operation.
Compatible with CAN bus for real-time working status feedback, and built-in overload protection function, which can effectively prevent system faults caused by abnormal pressure and extend the service life of valves and actuators.
