Van điện, electric actuator,AS-25/K30H
The AS-25 is a specification of the Bernard SD series. It has 220V and 380V power supply. The special supply voltage needs to be customized.
Model table:
First, SD series intelligent electric actuators use :
SD series intelligent angular travel AS-25 electric actuator can be used to control various types of valves with 90 degree angles such as butterfly valves, ball valves, louver valves, dampers, plug valves, flapper valves, etc.
Second, the type and form of the product:
AS-25 is a quarter-turn electric actuator - output torque, 90 ° angle.
2. SD series electric actuators are divided into two types according to the installation method:
a. Direct connection type - directly connected to the valve through the flange of the output part of the actuator, so that the actuator can be directly installed on the pipe. Used for multi-turn, angular travel, straight stroke.
b. Base type—The actuator is connected to the valve through a lever. At this time, the actuator needs to be mounted on a base pedestal, and only the angular stroke is installed in this way.
1. The SD series electric actuator adjustment mode is divided into three types:
(1) Proportional adjustment type——The actuator receives the analog signal of 4~20mA or 0~10mA determined by the computer, regulator, etc., and the output shaft angle (or displacement) of the actuator is proportional to the signal, and the adjustment is automatically completed. task.
The proportional-regulated electric actuator is divided into two types in terms of structure and installation.
a. The integral proportional adjustment type, that is, the actuator and the position locator GAMX-D are assembled into one whole, and the whole machine is installed on site.
a. Discrete proportional adjustment type, the actuator is also composed of actuator and position locator, but the actuator is installed separately from the position locator GAMX , and the position locator is installed indoors or elsewhere.
Note: The integral and discrete external wiring are not the same.
(2) Remote control type - also called integral type, the actuator receives the pulse signal and the relay signal, and can control the output shaft of the actuator at any position.
Switch type - also known as two-position, it receives the switching signal, but the output shaft of the actuator can only be controlled in the open and
(2) Close the two extreme positions.
(4) The integral adjustment type electric actuator is actually a remote control type equipped with a separate installation GAMX position locator. Here, it is specially stated that the circuit principle, external wiring and adjustment method are the same regardless of the angular stroke, straight stroke and multi-turn electric actuator. You should pay more attention to the power supply, voltage, installation method, output torque and stroke when selecting the type. Whether the signal meets your requirements.
Third, the main technical indicators:
The following technical indicators are mainly applicable to the proportional adjustment type. For the remote control type and the switch type, the following examples 1 , 2 , 3 , 4 , 5 , and 6 are not involved.
1. Input signal: 4~20mA (or 1~5V ) DC, etc. 2. Input channel resistance: 250 3. Number of input channels: . 1 th (as discrete . 3 th) 4. Basic error: 1%, 2.5% 5. Backlash: ≤ 1.5% 6. Dead zone: 0.5%~3% continuously adjustable ( can be adjusted according to system requirements ) 7. Damping characteristics: no swing 8. Power supply voltage: three-phase 380V , 50Hz (or 400V , 50Hz );
Single phase 220V , 50Hz (or 230V , 50Hz ) 9. Working environment: Temperature : integral -25 ° C ~ +75 ° C , discrete -25 ° C ~ +85 ° C ;
Humidity : ≤ 85% ambient air does not contain corrosive properties . Protection Level: meet IEC14 IP65 ( i.e. rain and dust ) ; position locator GAMX meet IEC14 IP44 ,
( Except for discrete GAMX for indoor installation ) . 11. Break signal protection: When required, you can choose to fully open, fully close, and keep the original position. Generally, it is set to keep the original position when leaving the factory.
