Solenoid valve, type EV210B and EV210BW 2 Functions 2.1 Function NC Coil voltage disconnected (closed): When the voltage to the coil (5) is disconnected, the armature (2) with the valve plate (3) is pressed down against the valve orifice (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 orifice (4). The valve is now open for unimpeded flow and will be open for as...

Solenoid valve, type EV210B and EV210BW 3 Applications It is recommended to use a filter in front of the valve. Recommended filter 50 mesh (297 microns). Figure 3: 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 4: Exercise: Valve on/off 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...
