Electric Actuators

The JQ Series Electric Actuator from Jeongdo Machinery is equipped with a BLDC (Brushless DC) motor and features a compact, space-saving design. It is a high-performance, highly durable actuator engineered for reliable operation.
The actuator is supplied in configurations optimized for specific operating conditions, including system pressure and environmental requirements.
Integrated Control Board Design
The power supply, BLDC motor driver, and control board are fully integrated, achieving a compact and intelligent control system.
Optimized structure for butterfly valve actuation.
Enhanced Seating/Unseating Torque
Utilizes a Scotch Yoke mechanism, improving seating/unseating torque by 10–20% compared to conventional models.
High-Performance Brushless DC Motor
- Designed for high-speed, high-frequency operation, with low inertia and high stall torque characteristics. → Supports up to 300–1200 operations per hour (model dependent).
- Maintenance-free and highly durable motor design.
Reliable Actuation Mechanism
- Supports various systems: Worm Gearing, Hammer-Blow, Lead Screw, and Scotch Yoke.
- Features self-locking capability (single/double worm gearing).
- Built-in electronic torque sensing for automatic protection against overload or overheating.
Easy Limit Switch Adjustment
· For models JQ-020 and above: external bolt adjustment without disassembly.
· For models JQ-015 and below: simple setting by removing the top cap only.
