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
orice (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 orice 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.
