In fluid control systems in fields such as chemical engineering, electricity, and water conservancy, valves serve as the core actuating components, and their precision and reliability directly affect production efficiency and safety.The BIQ series electric actuators, with their intelligence, high precision, and strong adaptability, have become the "smart engine" in the field of industrial automation, providing efficient solutions for valve control under complex working conditions.

　　1、 Non invasive design: easy to operate, worry free maintenance

The BIQ series adopts a non-invasive structural design, and parameter settings, function debugging, and on-site operations can be completed through a handheld infrared remote control without opening the box cover. For example, in butterfly valve control of chemical pipelines, operators can adjust the valve opening through a remote control from 5 meters away to avoid contact with high temperature or corrosive media, ensuring safety and improving efficiency. Its dual sealing structure further prevents dust and moisture from entering, extending equipment life, especially suitable for outdoor or harsh environments.

　　2、 High precision positioning: micrometer level control to meet stringent requirements

Built in Hall sensors and digital encoders, the BIQ series achieves micrometer level precision control of valve position. Taking the boiler feedwater regulating valve in the power industry as an example, its positioning accuracy error is ≤ 1%, ensuring stable water flow and avoiding equipment loss caused by pressure fluctuations. In addition, the error rate of torque measurement is ≤ 5%, which can dynamically monitor abnormalities such as excessive torque and locked rotor, and intervene in a timely manner through alarm function to prevent valve jamming or motor burnout.

　　3、 Full function protection: safety redundancy, stable operation

The BIQ series integrates 13 protection functions and builds multiple security defenses:

1. Travel limit protection: prevents the valve from running beyond its travel limit;

2. Torque limit protection: Independent torque threshold is set for the on/off direction to avoid overload;

3. Motor overheating protection: Built in thermal protection switch, automatically shuts down when the temperature exceeds the limit;

4. Power failure protection: triggers an alarm and shuts down when there is a phase loss, phase drop, or voltage fluctuation.

In oil storage and transportation scenarios, these functions can effectively prevent leakage or explosion risks caused by valve failures.

　　4、 Multi scenario adaptation: flexible combination, covering the entire industry

The BIQ series offers three types: multi turn, angular stroke, and straight stroke, supporting customized combinations:

1. Multi turn: Suitable for gate valves and globe valves, with an output torque of up to 3000Nm;

2. Angular stroke: Connect butterfly valves and ball valves to achieve 90 ° rotation control;

3. Straight stroke: The trapezoidal nut screw converts rotational motion into linear thrust, driving the regulating valve.

　　5、 Intelligent interconnection: data-driven, remote control

Supporting 4-20mA analog signals, switch signals, and HART communication protocol, the BIQ series can seamlessly integrate with DCS control systems to achieve remote monitoring and fault diagnosis. Its 5 passive contacts can provide real-time feedback on valve status, assisting in the digital upgrade of factories. In the control of blast furnace gas regulating valves in the metallurgical industry, this function enables operators to adjust the valve opening in real-time in the central control room, optimizing combustion efficiency.

Conclusion

The BIQ series electric actuators are centered around "precision, safety, and intelligence", redefining the standards for industrial valve control through non-invasive design, high-precision positioning, full function protection, and multi scenario adaptation. From chemical pipelines to power boilers, from oil storage and transportation to cement production, it is playing the role of a "smart engine" to promote industrial automation towards a more efficient and reliable direction.
