The 3601L series linear electronic electric actuator is an intelligent control unit driven by a high-performance motor and integrated with a sophisticated control module. Designed specifically for linear stroke valves such as single-seated, double-seated, and cage-guided control valves, it features an integrated servo control system that eliminates the need for external amplifiers. It directly receives standard analog signals (e.g., 4-20mA DC) from systems like PLC or DCS. The core mechanism converts the motor's rotary motion into precise linear displacement of the thrust rod, enabling continuous proportional regulation of valve openings. Known for its high integration, accurate positioning, and reliability, the 3601L series is widely used in automated fluid control within the petroleum, chemical, power, and district heating industries.

1.Highly integrated electronic design:The built-in intelligent servo amplifier module simplifies control loop wiring. It supports fail-in-place logic and online calibration for zero and span, significantly enhancing anti-interference capability and stability.
2.High-precision linear displacement:Utilizing precision reduction gears and a lead screw mechanism, it ensures an excellent linear relationship between rod displacement and input signal. The minimal dead zone and high resolution meet strict process fine-tuning requirements.
3.Comprehensive intelligent protection:Integrated with overload protection, motor over-temperature sensors, and electrical limit logic. The system automatically cuts power and triggers alarms during stall or over-load events to protect the motor and internals.
4.Reliable mechanical self-locking:The transmission system provides excellent self-locking properties, reliably maintaining the valve position during power or signal failure to prevent drift caused by pressure fluctuations.
5.Manual and automatic override modes:Equipped with an emergency handwheel for manual intervention during power loss or commissioning. The switch between manual and auto modes is smooth, ensuring 24/7 operability.
6.Durable housing structure:The high-strength aluminum alloy casing features high-performance anti-corrosion coating. Rated at IP65 or above, it resists dust, moisture, and industrial corrosive gases in harsh environments.
7.Wide valve compatibility:The yoke interface design complies with international standards, allowing for easy adaptation to various global control valve brands. Stable thrust output and a wide stroke range allow for flexible selection.
8.Low maintenance and long service life:Core bearings and transmission parts are pre-lubricated for low mechanical wear. The modular electronic components facilitate easy replacement or upgrades, reducing long-term operational costs.
