Solenoid valve Type EV210A

Direct-operated 2/2- way solenoid valves for use in industrial machinery

EV210A covers a wide range of small, directoperated 2/2-way solenoid valves for use in industrial machinery.

The compact design together with the broad range of coils means that EV210A covers a broad variety of industrial applications.

Features and versions

• For water, steam, oil, compressed air, aggressive liquids and gases

• Screw on coil

• Ambient temperature: Up to 50 °C

• Coil enclosure: Up to IP65

• EV210A NC and NO versions in brass for neutral media

• EV210A NC stainless steel version for neutral and aggressive liquids and gases

2 Functions

2.1 Function NC

Coil voltage disconnected (closed):

When the voltage is disconnected, the armature (2) with the valve plate (3) is pressed down against the valve orice (4) by the closing spring (1) and the medium’s pressure.

The valve will be closed for as long as the voltage to the coil is disconnected.

Coil voltage connected (open):

When voltage is applied to the coil (5), the armature (2) with the valve plate (3) is lifted clear of the valve orice (4).

The valve is now open for unimpeded ow and will be open for as long as there is voltage to the coil.

2.2 Function NO

Coil voltage disconnected (open):

When the voltage to the coil is disconnected, the valve orice (6) is open, the opening spring (3) pressing the valve plate (7) clear of the orice (6) via the armature (4) and the pins (5). The valve will be open for as long as the supply voltage is disconnected.

Coil voltage connected (closed):

When voltage is applied to the coil, the armature (4) is drawn up to touch the xed top (2). The valve plate (7) is pressed against the valve orice (6) by the closing spring (8). The valve will be closed for as long as there is voltage to the coil.

3 Applications

It is recommended to use a lter in front of the valve. Recommended lter 50 mesh (297 microns).

Figure 1: Filter

In water applications, exercise the valves at least once every 24 hours, meaning change the state of the valve. The valve exercise will minimize the risk of the valve sticking due to calcium carbonate, zinc or iron oxide build-up.

Figure 2: Exercise: Valve on/o

To minimize scaling, and corrosion attack it is recommended that the water passing the valve have the following values:

• Hardness 6 - 18 °dH to avoid scaling (chalk / lime stone build up)

• Conductivity 50 – 800 µS/cm to avoid brass dezincication and corrosion

• Above 25 °C media temperature avoid stagnant water inside the valve to avoid dezincication and corrosion attack
