Actuator composition classification

I don’t know what specific classification of actuators you want to know. Butterfly valves and actuators are generally installed with flanges, and the valve shaft is connected with splines or flat keys through a machined coupling.

The classification of specific actuators

is for your reference: 1. Basic concepts of actuators

What are the three major categories of actuators according to their power energy forms?

They are pneumatic, electric and hydraulic.

Actuators can be divided into several categories according to the form of output displacement

Three major categories: multi-turn, angular stroke, and straight stroke. Arms can also be added.

It can be divided into several models according to the host computer signal control method

Switch type, regulating type, fieldbus type

Divided according to the mechanical structure composition

Basic execution unit

,

Gain unit,

Intelligent unit

7. Distinguished according to usage place and environment. auma actuators can be divided into

ordinary type

explosion-proof type

explosion-proof type

8. Distinguish auma according to the ambient temperature of use The actuator is also available

Standard type (-25℃......80℃)

Low temperature type (-40℃......60℃)

Ultra-low temperature Type (-60℃... 60℃)

High temperature (-0℃...... 120℃)

9. According to the sealing protection level, auma actuators can be Divided into

ip67: sink up to 1 meter underwater, work for 30 minutes

ip68; sink up to 6 meters underwater, place continuously for 72 hours, and operate underwater for 10 Times

10. According to the anti-corrosion environmental protection level, auma actuators can be divided into categories

kn: with high-quality coating, suitable for outdoor environments with slightly corrosive atmosphere

kn p>

ks: Suitable for corrosive environments with moderate pollution

kx: Suitable for highly corrosive environments with high pollution and high humidity

11 , according to load type, auma actuators can be divided into

s4-25

s4-50

s5-

12, The explosion-proof level is divided into multiple levels

exb or exc

Intrinsic safety type

Increased safety type

Explosion-proof type
