Description

The Electric Rotary Actuator 4-20mA is the actuator and control valve combination in the automatic control system. Its role in the automatic control system is to accept the signal from the regulator, to adjust the flow of the process medium in the position and characteristics of the process pipeline, so as to control the controlled number within the range required by the production process.

Working principle

At the gear stage, the engine speed can be transmitted to the output rod via two sets of gears. The final drive is made up of planetary gears and the secondary reducer is realized by a worm gear, which is held in a central position by a set of springs. In the event of an overload, that is, when the output rod exceeds the set torque of the spring, the central worm gear will axially shift, fine-tuning the switch and signal device to provide protection for the system.

Acted by the coupling of the externally controlled lever, the output rod is coupled to the worm gear during engine operation and coupled to the handwheel during manual operation. When the engine is not working, the motor drive can be easily disconnected and the handwheel can be connected by simply pressing the lever. Since the motor drive takes precedence over manual operation, a reverse action occurs automatically when the engine is started again. This will prevent the handwheel from turning on when the engine is running, which will help protect the Electric Rotary Actuator 4-20mA.

We try to acquire each customer's rely on for on off Type Intelligent Regulator 4-20mA Mini Rotary Electric Actuator. With a strong sales network and a complete after-sales service system, our products have taken the initiative in the fierce market competition. We realize that providing high-quality and high-performance products is a very important success factor for a company to establish long-term cooperative relationships with customers.
