Data Sheet

Solenoid valves
Type EV212B

Direct operated with isolated diaphragm for dirt and aggressive uids

The isolating diaphragm design ensures that no
uid enters the armature area which means
valves can be used for

• aggressive uids

• uid with impurities

• uid with risk of lime stone build up

Applications

• Marine ballast water treatment systems

• Dosing systems

• Pump cooling fx. Vacuum systems

• Systems with particles (Dirt) and aggressive

(sample intake)

◦ Washing and cleaning systems (Alkaline)
◦ Filling

media

Features

• Stainless steel body

• Clip on coil

• Viscosity: up to 50 cSt

• Ambient temperature: up to 50 °C

• Coil enclosure: up to IP67

2 Functions

2.1 Function

Function NC

When voltage is applied to the coil (5), the armature (2) with the isolating diaphragm (3) is lifted clear of the valve
orice (4) and opens for ow through the valve. The valve is open as long as there is voltage to the coil.

When voltage is disconnected, the isolating diaphragm (3) is pressed down against the orice by the spring (1). The
valve will be closed for as long as the voltage to the coil is disconnected. The isolating diaphragm keeps the
medium away from the actuator.

The space above the isolating diaphragm is lled up with silicone oil.

Solenoid valves, Type EV212B

3 Applications

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

Figure 2: 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 3: 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.
