Normally Closed SS304 Solenoid Armature Assembly Application For Pneumatic Solenoid Valve/Solenoid Stem

Feauture and characteristic

1.Three way two positon normally closed solenoid stem/Plunger tube assembly.This type of solenoid armature has three ports and Two position including the input and the output.

2.This item use mental material-stainless steel/SS304 except the NBR Seal.

SS304: 304 stainless steel is a common stainless steel material, 7.93 g/cm 3 density, also known as 18/8 stainless steel industry. High temperature resistance , with good processing performance, high toughness characteristics, widely used in industrial and furniture decoration industry and food and medical industry.

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

3.With male thread in the top place of armature,connecting the solenoid coil/solenoid coil housing by fitting the thread.

4.Has circular Thread Seat as the connection as well.

5.The plunger and spring is a bit little uncommon.External spring and interior spring coexist,providing enough spring force when de-energized and hold the solenoid stem easily.Plunger shape is different from the common plunger.Except the NBR seal in the top and bottom,there are four grooves and one vent in the surface of the plunger.And the shape of bottom of the plunger is similar to a fan.

Application and purpose

1.Mainly used for solenoid coil.A part of the solenoid valve/solenoid armature/pneumatic solenoid valve

2,After assembling,The pneumatic solenoid valve controls the movement of the valve body to stop or leak out different oil drainage holes, and the oil intake hole is normally open. Hydraulic oil will enter different oil drainage pipes. And drive the piston cylinder through the pneumatic solenoid valve oil pressures. pneumatic solenoid valve solenoid current control the entire Mechanical movement of solenoid valves when energized

The advantages and disadvantages of pneumatic solenoid valve

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

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.

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.
