Introduction of Quarter-Turn Electric Valve Actuator BJ10-Q1 Intelligent Series

Quarter-Turn Electric Valve Actuator Intelligent Series BJ10-Q1 serve as high-performance quarter-turn drive units built for modern industrial fluid control systems. These actuators deliver steady and dependable motion for ball valves, butterfly valves, and other 90° rotating valves, and they fit smoothly into power generation, petroleum, chemical, metallurgy, environmental protection, and municipal engineering applications. With a rugged yet lightweight aluminum alloy housing, they feature a compact structure, small size, attractive appearance, and consistent long-term performance, making installation and daily operation both flexible and reliable.
Furthermore, BJ10-Q1 integrate rich intelligent functions to simplify on-site use and enhance safety. They support self-diagnosis, automatic phase sequence correction, and complete overload and fault protection, which greatly reduce wiring errors and unexpected downtime. Users can choose from multiple control modes, including local operation, remote on-off control, analog regulation, ESD safety control, and fieldbus communication, so the actuators adapt easily to both basic switching tasks and high-precision continuous modulation jobs.
In addition, these actuators follow the ISO5211 standard mounting interface to ensure broad compatibility with most valve bodies. They come with IP65 protection and a dual‑seal structure to resist dust, moisture, and temperature changes in harsh working environments. All in all, BJ10-Q1 combine sturdy mechanics, smart electronics, and user-friendly operation, delivering stable, efficient, and safe automatic valve control for a wide range of industrial systems.

Dot-Matrix LCD Display
Quarter-Turn Electric Valve Actuator BJ10-Q1 Intelligent Series use a high‑definition dot-matrix liquid crystal display to optimize human-machine interaction. The screen shows real-time valve position, limit settings, operating status, and fault alarms in clear Chinese characters, numbers, and graphics. Meanwhile, the layout is straightforward and easy to read, even in dim on-site lighting.
In addition, the display integrates multiple data streams into one intuitive interface, so operators grasp full working conditions at a glance without extra tools or complex steps. Whether for routine checks or quick fault handling, the dot-matrix LCD keeps information visible and accurate. As a core part of BJ10-Q1 actuator, this display lowers operational difficulty and improves daily maintenance efficiency significantly.

Non-Intrusive Design
A key advantage of Quarter-Turn Electric Valve Actuator BJ10-Q1 Intelligent Series is their non-intrusive operating design that revolutionizes field setup and maintenance. Users adjust parameters, check signals, and query status through an independent programmer or field knob, with no need to open the enclosure.
As a result, the actuator retains full sealing performance and blocks dust, humidity, and pollutants from entering internal parts. Moreover, input and output current calibration and signal query also happen without disassembly. This design saves time, boosts on-site safety, and reduces wear from repeated cover removal. In short, the non-intrusive structure makes BJ10-Q1 Actuator more convenient, durable, and reliable for industrial sites.
Absolute Encoder Position Sensor

Quarter-Turn Electric Valve Actuator BJ10-Q1 Intelligent Series adopt high‑precision absolute encoder position sensors for stable and accurate valve position detection. Unlike traditional encoders, these units capture absolute angular position directly and keep data even after power loss.
Consequently, the actuator recognizes the exact valve position immediately on restart, avoiding position drift or repeated homing. Additionally, the sensor offers strong anti-interference performance and high resolution, maintaining precision under vibration or voltage fluctuation. It feeds accurate position data continuously to support smooth and stable valve control. The absolute encoder greatly strengthens the reliability of BJ10-Q1 Intelligent Series, making them perfect for unattended and high-demand automatic control systems.
