Introduction of Quarter-turn Electric Actuated Ball Valve BJ120-Q1 Series
The Quarter-turn Electric Actuated Ball Valve BJ120‑Q1 offers reliable, intelligent heavy-duty ball valve automation. Specifically, this device provides stable torque for precise 90° rotation. Consequently, users achieve consistent sealing and stable flow control under continuous operation. Moreover, multiple smart functions and robust protection enhance operational safety significantly. Furthermore, the actuator automatically diagnoses faults and alerts operators in real time.
A high-strength aluminum alloy housing features a dual-sealing structure. Therefore, this design blocks dust, moisture, and corrosive media effectively. As a result, the valve maintains stable operation in harsh outdoor or humid environments. Additionally, non-intrusive setup allows parameter changes without opening the cover. Hence, this feature greatly improves onsite efficiency and safety. The housing also resists UV damage and extreme temperatures for long-term reliability.
Various control modes and communication options support flexible DCS or PLC connection. Accordingly, both basic on-off control and precise regulating tasks benefit from excellent motion accuracy. The actuator also supports Modbus, Profibus, and Foundation Fieldbus protocols. Finally, long-term durability makes this valve suitable for petroleum, chemical, power, metallurgy, and water treatment industries. These sectors rely on its consistent performance for critical process control.

Fieldbus Communication Module
To meet the needs of intelligent factory networking, Quarter-turn Electric Actuated Ball Valve BJ120‑Q1 can be equipped with an optional fieldbus card module, supporting Modbus, Profibus‑DP, HART, DeviceNet, and FF protocols. This modular design allows quick plug‑and‑play installation without complicated rewiring. Meanwhile, it realizes real‑time data transmission, remote parameter setting, and status monitoring, helping users build a fully digital control system.
>Moreover, the bus module ensures stable signal transmission and strong anti‑interference ability, even in complex industrial environments with high electromagnetic interference. It also supports fault feedback and status upload, enabling the control room to grasp operating conditions at any time.
Non‑Intrusive Design
The non‑intrusive design is one of the core advantages of Quarter-turn Electric Actuated Ball Valve BJ120‑Q1. All stroke settings, torque adjustment, control mode switching, and signal calibration can be finished via an external knob or independent programmer, without removing the housing cover. This not only avoids dust and water intrusion during commissioning but also reduces potential risks in flammable, explosive, or humid working areas.
In addition, this design simplifies daily maintenance and troubleshooting, allowing on‑site staff to complete checks and adjustments quickly. It effectively shortens downtime and improves overall system efficiency.
Application Scenario Adaptability
Quarter-turn Electric Actuated Ball Valve BJ120‑Q1 performs excellently in diverse application scenarios, including process pipelines, boiler systems, environmental protection equipment, and municipal water supply networks. It adapts well to wide temperature ranges, high humidity, and occasional vibration, maintaining stable torque output and reliable action.
Furthermore, its standard ISO5211 flange interface ensures easy installation with most ball valves, reducing matching costs and installation time. Whether in fixed plants or mobile equipment, it provides consistent and stable driving performance.
Comprehensive Protection System
This Quarter-turn Electric Actuated Ball Valve BJ120‑Q1 is equipped with a complete set of protection functions, including torque overload protection, travel limit protection, phase loss protection, motor overheat protection, instantaneous reverse protection, and electrical isolation. These functions work together to prevent equipment damage caused by misoperation or abnormal working conditions.
Meanwhile, it supports automatic phase sequence correction, allowing users to connect power wires freely without worrying about phase errors. All protection mechanisms are real‑time and automatic, greatly improving operational safety and extending service life.
