Non-Intrusive Multi-turn Electric Actuator BD300-C6 features a highly humanized handwheel design for reliable emergency manual control. For safe and easy operation, you simply pull the anti‑tamper pin and push in the handwheel to start manual driving. The mechanism locks automatically during use and effectively prevents incorrect manual operation. In addition, it provides a stable and reasonable drive ratio for effortless and labor‑saving rotation. For enhanced security, it adds dedicated padlock holes to block any unauthorized operation. After manual operation completes, the handwheel pops up automatically and resets the whole structure smoothly. Furthermore, handwheel keeps electric mode and manual mode fully independent to ensure safe and interference‑free switching. You can achieve quick and reliable switch between power drive and manual drive at any time. Even in sudden power failure or system breakdown, it ensures continuous and stable valve control without interruption.

Non‑intrusive multi‑turn electric actuator fits numerous heavy‑duty industries and delivers consistent performance across demanding scenarios. First of all, it operates reliably in power plants and handles large valve regulation with strong torque output. It withstands corrosive surroundings to keep stable running in harsh petroleum and chemical systems. Metallurgical sites full of dust and vibration pose no challenge thanks to its strong adaptability. It also runs smoothly in marine engineering and light food processing with high hygiene standards. The actuator fits papermaking, construction and municipal engineering well and supports long‑term continuous work. It provides accurate and steady valve control for environmental protection equipment with strict demands. It keeps multi‑turn valves under precise control during uninterrupted operation. With its robust structure, it fully meets the strict safety and stability requirements of all key industrial sectors.

The BJ/BJM‑IIC series serves as a core field control device for modern industrial process systems. Thanks to patented planetary gear transmission, it delivers more than 50% higher mechanical efficiency and doubles the service life compared with traditional worm‑gear designs. In addition, it offers a wide torque range from 50N.m to 3000N.m and supports 0‑90° angular rotation to match ball valves, butterfly valves, and damper baffles perfectly. Moreover, it adopts a non‑intrusive operation structure that lets users set parameters and check status via knobs or infrared tools without opening the electrical cover. Furthermore, its double‑sealed die‑cast aluminum housing reaches IP68 protection and withstands dust, moisture, and long‑term underwater immersion.

Beyond structural advantages, the series integrates rich and flexible control functions to satisfy diverse project demands. For example, it supports local control, remote switching, analog adjustment, ESD emergency control, and multiple fieldbus communication modes. At the same time, it equips a high‑definition dot‑matrix LCD to display valve position, torque, and alarms in clear Chinese or English menus. Additionally, non‑contact absolute encoding sensors maintain accurate position data even after power loss without battery support. Equally important, complete protection systems cover overload, phase loss, motor overheat, and valve jamming to ensure stable running. Finally, it suits power, petroleum, chemical, metallurgy, marine, and environmental protection fields, and offers explosion‑proof and split‑type versions for harsh working conditions.
