BD150-C8 uses a standard 380Vac±10%/50Hz±2% three-phase three-wire power supply. Users can customize special power configurations when ordering to match specific industrial power grids, such as single-phase 220Vac or non-standard frequency, ensuring perfect compatibility with different regional power systems.It adopts an intermittent duty mode with a maximum working frequency of 60 times per hour. It limits continuous working time to no more than 15 minutes and controls the duty cycle below 33.3% during normal operation. This scientific design is tailored to the working characteristics of multi-turn valves, avoiding excessive energy consumption and component fatigue.This design avoids equipment overheating and component wear, thereby extending the product’s service life. The internal electrical components are selected from high-quality brands, with strong anti-interference ability, ensuring stable operation even in industrial environments with complex electromagnetic signals.Travel Control Mechanism
Functional Configuration
BD150-C8 Multi-turn Basic Type Electric Actuator comes standard with a reliable travel control mechanism and a field-adjustable position indicator. The travel control mechanism consists of high-precision gear sets, a wear-resistant cam, a transmission rod and high-sensitivity microswitches, with high wear resistance and long service life.Workers can preset the travel according to valve stroke requirements, and clear scale marks simplify on-site commissioning and calibration. The calibration process is simple and fast, reducing the time cost of on-site debugging and improving work efficiency.Its control error remains within ±1% to ensure precise valve position control. This high precision can effectively avoid valve leakage or poor sealing caused by inaccurate position control, ensuring the stability of industrial production processes.
Protection Performance
Multi-turn Basic Type Electric Actuator BD150‑C8 comes with IP67 protection as standard, and furthermore offers optional IP68 protection to better adapt to harsh outdoor environments. In addition, it supports explosion‑proof customization to meet the strict usage requirements of hazardous areas, including petrochemical workshops, coal mines, and chemical storage facilities.Moreover, its explosion‑proof grade reaches Ex db IIC T4 Gb and Ex tb IIIC T130℃ Db, which fully complies with international safety standards for hazardous zones. At the same time, the entire explosion‑proof structure has passed strict mechanical and electrical tests, which can effectively prevent internal sparks from igniting external flammable gases or dust, thus ensuring safe and stable operation in high‑risk environments.Besides, the actuator is also equipped with additional over‑torque and overload protection functions. Specifically, it can automatically cut off the power supply when abnormal working conditions occur, thereby ensuring the safety of on‑site operation and equipment. In turn, these comprehensive protection measures can effectively avoid actuator damage caused by valve jamming or power grid fluctuations, and greatly reduce later maintenance costs.
Application Scope
Thanks to its excellent environmental adaptability, Multi-turn Basic Type Electric Actuator BD150-C8 widely applies to multiple industries. Firstly, it serves the power industry to drive water supply, drainage and steam valves in thermal and hydropower plants, ensuring stable power generation processes and improving the efficiency of power unit operation.Secondly, it fits petrochemical facilities to control oil and chemical medium pipelines, and its explosion-proof version effectively reduces leakage and combustion risks. It can stably control the flow of various chemical media, ensuring the safety and continuity of petrochemical production.Additionally, it applies to municipal engineering and environmental protection projects to operate water treatment and flue gas treatment valves. It helps realize automatic control of water supply and sewage treatment, and assists in flue gas desulfurization and denitrification, meeting environmental protection emission requirements.Field Application of Split-Type Actuators
