HVQR series
The HVQR Series is a high-performance power-off reset electric actuator independently R&D by Yangzhou Hengchun Electronic Co., Ltd., a leading China-based manufacturer of industrial valve actuators. As a dedicated industrial electric actuator with integrated energy storage, it features a built-in battery/capacitor energy storage device that enables automatic power-off reset functionality. Exclusively engineered for matching small-caliber gate valves, globe valves, butterfly valves and other common industrial valves, this actuator can rapidly drive valves to a preset safe position in the event of sudden power failure or emergency equipment fault, effectively avoiding industrial safety hazards. Compact in structure and easy to install, the HVQR Series battery/capacitor reset-type electric actuator has become a core component for automatic valve control in various heavy industries, with reliable performance verified by practical application scenarios.
Powered by an internal battery/capacitor energy storage system. The actuator realizes fast and accurate valve reset without external power supply when power failure or emergency fault occurs, ensuring industrial process safety.
Optimized for small-caliber gate, globe and butterfly valves. It matches most standard industrial small-diameter valves with flexible connection modes, reducing secondary adaptation costs.
With structural sealing and anti-corrosion design, it is resistant to humidity, vibration and dust. Adapting to the complex working environments of petroleum, chemical and marine fields.
The integrated structural design saves installation space. The standardized interface is easy to connect with valve systems, shortening on-site commissioning time.
