Ruiji-RL intelligent corner stroke

1、Overview

The angle stroke electric actuator, as an important field control device in the automatic control system, adopts a direct connection and can be easily matched with rotary valves (such as butterfly valves, ball valves, plug valves) and dampers, etc. Its output angle displacement is 0110° or other angles, and it can be widely used in power stations, metallurgy, petroleum, chemical industry, water conservancy, machinery, light, fire protection and environmental protection and other industrial departments. The RL series electric actuators are designed to be simple and compact, covering 13 varieties and specifications, can provide the most reasonable solution within the output torque range of 60N.m∽2500 N.m. This series of electric actuators are intelligent can be equipped with various functional configurations according to user requirements to meet the requirements of various industrial process control. The standard type shell and box body treated by phosphating and coating can adapt to corrosive working environment, and the explosion-proof products with explosion-proof and pressure-resistant structure provided in the form of accessories can be used in dangerous working such as places with explosive mixtures of IIA, IIB, IIC grade T1-T4 grade.

3、 Function and performance and features introduction The RL series intelligent angle stroke electric actuator can be quickly set, checked and inquired by separate explosion-proof type setter without invasion. The graphic dot matrix LCD display is used to display the working status and alarm of the actuator, such as torque, valve, limit setting, etc., in the form of Chinese, numbers and graphics. At the same time, it supports multiple languages such as Chinese and English, and the can be switched through the menu. The absolute position encoder technology is used, and the LCD display and valve position detection are supported by the backup battery in the case of power failure.
