Ruiji-RQMⅢ series electric actuator

1.Overview

The new generation of intelligent RQMⅢ series electric actuators can be quickly set, checked, and inquired nonvasively through an independent setter. The actuator uses a graphic dot matrix LCD display to show the working status and alarms such as torque, valve position, limit setting etc., in Chinese, numbers, and graphics, as shown in Figure 1-1, which greatly facilitates the user's operation and use. The actuator has protection functions and explosion-proof functions. Even in hazardous areas, it is not necessary to open the cover of the electric box of the working actuator to adjust and diagnose. By using the fieldbus communication card, a fully distributed computer collaborative working system can be formed to achieve remote communication, remote collection, remote diagnosis, and maintenance. to its advanced, reliable, and convenient operation, it is welcomed by a wide range of users and is widely used in industries such as petroleum, electricity, metallurgy and water treatment.
