Introduction of Part-Turn Intelligent Electric Actuator BJ120-Q3
Part-Turn Intelligent Electric Actuator BJ120-Q3 serves heavy-duty drive needs for medium and large-bore industrial valves. To begin with, optimized internal transmission and refined motor layout deliver steady, abundant rated torque, and match large-size butterfly valves, ball valves as well as regulating valves for heavy industrial projects. Furthermore, complete intelligent control system gathers automatic phase correction, torque overload defense and anti-jam protection, and safeguards steady, secure valve movement. Meanwhile, compact structural design raises overall load capacity, and facilitates quick field installation alongside standard flange assembly.
Part-Turn Intelligent Electric Actuator BJ120-Q3 prioritizes environment adaptability and long-term operational stability. Firstly, premium lubricant and upgraded gear structures lower mechanical abrasion and prolong service life under frequent cyclic work. Besides, outstanding sealing design supports optional explosion-proof and dustproof configurations for dangerous chemical zones and dust-filled workshops. Finally, ISO5211 standard flange structure realizes versatile installation in various industries.

Core Intelligent Hardware Configuration
Part-Turn Intelligent Electric Actuator BJ120-Q3 is equipped with professional intelligent hardware, so it fully supports high-load and high-precision valve control. First of all, it fits expandable fieldbus card to access multiple industrial bus systems, and hence finishes remote data transmission and real-time command interaction. Besides, it embeds high-stability absolute encoder to realize high-precision valve position detection; meanwhile, this component keeps position memory after power off, and accordingly removes position deviation after equipment restart.
Wide Range Application Scenarios
In addition, Part-Turn Intelligent Electric Actuator BJ120-Q3 is widely applied in heavy industrial fields, and thus perfectly satisfies various working demands requiring medium and large output torque. For one thing, onsite process pipeline control covers chemical, electric power, metallurgy and environmental protection industries, meanwhile fulfilling practical valve driving needs from municipal water conservancy, sewage disposal and marine engineering projects. For another, different working surroundings ranging from indoor workshops to exposed outdoor fields suit its operational features well, so the whole equipment can sustain stable, durable and consistent operating performance throughout the whole year.
