Introduction of Quarter-turn Intelligent Actuators BJ90-Q1
The Quarter-turn Intelligent Actuators BJ90-Q1 are a crucial on-site device for precise and efficient process control. As the core executive component connecting the control system and pipeline valves, it isthey are widely applied in various industrial scenarios that require precise control of fluid media, effectively realizing the automatic regulation and on-off control of pipelines, thus ensuring the safe and smooth operation of the entire production process. Adopting high-quality aluminum alloy housing, our actuators feature a compact structure, small size, light weight, elegant appearance, as well as reliable and stable performance. What’s more, our products support on-site independent installation by operators, with fast and non-intrusive configuration, fault diagnosis and data query functions. In addition, each actuator is equipped with a matrix LCD screen, which can display valve position, limit parameters, operating status and fault information in multiple languages through numbers and graphics, ensuring clear reading in various application scenarios.
What are Quarter-turn Intelligent Actuators?
As a professional supplier, we define quarter-turn intelligent actuators as devices that realize remote and local control of pipeline shut-off valves—these valves adopt a quarter-turn shut-off structure. Our quarter-turn electric actuators are widely used in various public utility and industrial fields, including gas, petroleum, metallurgy, food processing, and other public utility operations, providing stable and efficient control solutions for different industries.
Quarter-turn Intelligent Actuators BJ90-Q1 series cover an excellent torque range of 50 to 5000 N·m, and play an irreplaceable role in key industries such as power generation, oil and gas, chemical processing, metallurgy, shipbuilding, light industry, food processing, pulp and paper, construction, municipal engineering, and environmental protection systems. We have always been committed to providing targeted torque solutions for different industrial scenarios to meet diverse user needs.
In terms of interface flanges, Quarter-turn Intelligent Actuators BJ90-Q1 series strictly comply with the ISO5211:2001 (GB/T12223-2005) standard. At the same time, we can customize and match non-standard flanges according to the specific requirements of users, fully reflecting our customer-oriented service concept.
Quarter-turn Intelligent Actuator Characteristics
How does Quarter-Turn Intelligent Actuators work?
The operating principle of our electric actuator control valve is simple and easy to understand. The actuator works according to the electrical signal sent by the control system—this signal can come from thermostats, pressure sensors and other equipment that monitor system parameters. After receiving the signal, the actuator drives the valve to complete the quarter-turn action, realizing the opening and closing control of the pipeline.
What makes Quarter-turn Intelligent Actuators BJ90-Q1 series stand out is that they support user-defined status feedback signals. Users can calibrate the input and output current and query the input signal without opening the actuator cover. This non-intrusive operation design greatly improves the convenience of operation and avoids equipment damage caused by frequent opening of the cover.
Perfect Product Protection
We greatly value product safety and service life. Therefore, we equip the BJ90-Q1 series with a full range of protection mechanisms. These include valve limit protection and torque overload protection. We also add automatic phase correction and instant reverse protection. Moreover, we provide phase loss protection and valve jamming protection. In addition, we incorporate motor thermal protection and electrical insulation protection. As a result, these multiple functions comprehensively protect all equipment components. Accordingly, they guard against various potential risks. Thus, we ensure long-term stable operation of the product.

The BJ-Q3 series actuator has a compact, light, and nice-looking body. Moreover, it works reliably and supports fast, non-intrusive setup and checks. For user convenience, operators can use either a handheld setter or a local adjustment knob. Meanwhile, a dot-matrix LCD shows position, limits, status, and warnings clearly. Specifically, it uses Chinese text, numbers, and graphics for easy understanding.
As for torque, the BJ10-Q3 covers an output range of 50–5000 N·m. Consequently, it serves many industries, including power, petroleum, chemical, metallurgy, and shipbuilding. Additionally, it also works for light food processing, papermaking, construction, and municipal projects.
Furthermore, optional communication cards like Modbus, Profibus-DP, HART, DeviceNet, and FF are available. Accordingly, these cards enable smooth fieldbus connection for the actuator. For extreme conditions, the BJ10-Q3F split-type actuator is a good choice. In this design, it puts the B-F control unit in a separate remote cabinet. Finally, a connecting cable links the control unit and actuator for more flexibility.
