Quarter-Turn Electric Valve Actuators BJ15-Q1 Intelligent Series are compact, high‑reliability rotary drive units designed for precise valve control in heavy‑duty industrial processes. Engineered for ball valves, butterfly valves, plug valves, and other quarter‑turn control components, these actuators deliver a rated torque of 150 N·m with selectable output speeds of 0.5 rpm and 1 rpm, making them ideal for on‑off and light modulating duty across power, petroleum, chemical, metallurgy, water treatment, and municipal engineering systems. They operate steadily under continuous working conditions and maintain consistent performance even in long‑term use, bringing stable and dependable drive support to various fluid control scenarios.

Built with a rugged aluminum alloy housing, they combine low weight, high structural rigidity, and modern aesthetics, while complying with ISO5211 standard mounting flanges for fast installation and broad valve compatibility. Moreover, BJ15-Q1 supports multiple control modes, including local operation, remote switching control, analog regulation, ESD emergency shutdown, and two‑wire control, to fit diverse system architectures. It also integrates full‑featured protection: torque overload, motor overheating, phase loss, automatic phase correction, and instantaneous reverse prevention, all working together to boost operational safety and extend service life.

Additionally, the series supports optional communication bus cards and non‑intrusive setup, simplifying on‑site commissioning, calibration, and routine maintenance. As a core component in automated flow control loops, BJ15-Q1 reliably links electrical control signals and mechanical valve motion, enabling stable, efficient, unattended operation, reducing manual intervention, and improving overall process safety and reliability. It effectively lowers daily management costs and enhances the stability and intelligence level of the whole control system.

Specification of Quarter-Turn Electric Valve Actuator BJ10-Q1 Intelligent Series

The Quarter-Turn Electric Valve Actuators BJ15-Q1 Intelligent Series has a user‑centric non‑intrusive design. Meanwhile, it simplifies field setup for quarter‑turn valve actuators. Specifically, technicians need not open electrical covers or expose circuits. Instead, they set parameters via an external setter or control knob. Also, limit setting and calibration are done directly on the enclosure. Thus, this keeps moisture, dust and corrosive gases out of the unit. Moreover, it maintains the IP65 ingress protection rating effectively. Additionally, it also reduces short circuits and component damage risks. Furthermore, non‑intrusive operation supports fast signal calibration. Besides, no wiring disassembly is required during the process. Therefore, this saves time and minimizes potential human error. Notably, the non‑intrusive design is particularly useful in harsh or explosive environments. In fact, safe setup is possible without breaking the sealed enclosure. Consequently, the design makes the actuator more convenient and reliable. Finally, it also improves adaptability to tough field conditions.
