How to Choose an Electric Actuator?

Users in the valve electric device selection, are the first to understand the type of valve, the device’s operating specifications, and the location of the valve in the pipeline or equipment.

And then ask about the functional requirements of the electric head, the need to pay attention, including determining the IP protection level of the electric device, electric power supply voltage, knowing the electric device operating time, determining the form of the electric actuator, additional features, and so on.

The valve electric head is one of the driving devices used to operate the valve automatically and is connected to the valve. The valve electric device is driven by electricity, and the motion process of the valve electric head is controlled by the size of the stroke, torque, or axial thrust.
Valve electric head classification has two categories, according to the type of protection can be divided into ordinary electric devices and special protection type electric devices.

The use environment of ordinary-type electric devices is as follows:

(1) Ambient temperature -25-40 ℃;

(2) Ambient relative humidity ≤ 90%. (at 25℃);

(3) Altitude ≤ 1000m;

(4) The working environment does not contain corrosive, flammable, explosive media.

If the valve’s working environment conditions exceed the ability of ordinary electric devices, need to use special protection type electric device products. This type of electric device products according to its working environment and has a variety of types.
