Classification and use of SD products.

SD non-intrusive intelligent electric actuator is the execution unit in industrial automation instrument, it 

receives from the regulator, PLC, DCS control signal from the computer, such as the completion of automatic 

adjustment, is indispensable to automatic control system for main equipment. It is widely used in power 

station, metallurgy, petroleum, chemical mine, light industry, pharmacy, gas power, building materials, 

transportation and city subway, water supply, sewage treatment and other industries.

Electric actuators are classified according to output.

Quarter turn actuator.

Also known as part of the return receipt actuators, general rotation range of 0-90°, the output torque in Nm.

 Mainly used for: butterfly valve, ball valve, shutter type valve, damper, baffle and plug valve.

Linear-turn actuator.

The output is indicated by N, and the output is a linear displacement.Mainly used for single, double seat 

control valve, sleeve valve, gate valve, etc.

Multi-turn actuator.

Output torque in Nm, more than 360°rotation. It is mainly used for gate valve, globe valve, slide valve, 

high temperature and high pressure regulating valve, etc.

Note: 1.The electric actuator required by the special technology needs to write clearly and concretely in 

order.

2.When A+RA300/K30HGP model is A+RS, the working torque is 1000Nm, single-phase power supply, 

the whole travel time is 30 seconds, and foot-plate installation with integration proportional modulatin with 

the local operation.
