High Quality 29.0mm Depth Armature Stem/NBR Seal Pentagon Seat Solenoid Stem

High Quality 29.0mm Depth Armature Stem/NBR Seal Pentagon Seat Solenoid Stem

Material we use in this item

1.Armature:Stainless steel 430

2.plunger and spring:Stainless steel 430

430FR:430 stainless steel is a kind of universal steel with good corrosion resistance. Its thermal conductivity is better than austenite, thermal expansion coefficient is smaller than austenite, and thermal fatigue resistance is better. The mechanical properties of weld seam are better when adding stabilized element titanium.

3.Seal:NBR

4:O-Ring:NBR

NBR:has good resistance to mineral oils, vegetable oils, benzene/petrol, ordinary diluted acids and alkaline.

Different type of solenoid valve(This item could be assembled  with the 13.0OD 35.0mm tube height solenoid coil)

Therer are noramlly closed or normally open type.More concretely,the solenoid valve is divided into 2/2 way noramlly closed,2/2 way normally open,3/2 way normally closed,3/2 way normally open

Though have a bit little differences,their work principle are same.

Working principle:when the valve is powered,Interior space of the solenoid valve creat a electromagnetic field which let the ports open and close.Then the media of liquid will flow because the movable is upward.

Application and purpose

1,This item mainly use for pneumatic solenoid valve

Pneumatic solenoid valve advantages:

1.1,In vacuum, negative pressure, zero pressure can work normally, but the diameter is generally not more than 25 mm.

1.2,It can also be operated at zero differential pressure or vacuum or high voltage, but the power is large, so it must be installed horizontally.

1.3,The upper limit of fluid pressure range is high, and can be installed arbitrarily (to be customized) but must meet the fluid pressure differential conditions.

2.With changing the shape and size,solenoid stem also could be used for other aspects.

For instance:Solenoid valve can be used not only in pneumatic system, but also in oil pressure system and water pressure system. For example, small solenoid directional valve with low power and no oil supply can be used in food, medicine and electronics industries. With the continuous progress of technology, electromagnetic valve technology and control technology, computer technology, electronic technology, has been able to carry out a variety of complex control. For example, electromagnetic valve can be used in the field of intelligent control, wireless control technology and so on. Solenoid valve is precisely because it can be controlled by electromagnetic, so it can be a good interface of various electronic systems, which is also a major reason why it has been widely used.
