Solenoid valve, type EV310B 2 Functions 2.1 Function, NC Coil voltage disconnected (closed): When the voltage to the coil is disconnected, the armature with the valve plates is pressed down by the closing spring and closes the connection between P and A. At the same time, the connection between ports A and R is opened. The connection between P and A will be closed for as long as the voltage to the coil is disconnected. Coil voltage connected (open): When voltage is applied, the armature with the valve plates is lifted and closes the connection between A and R. At the same time, the connection...

Solenoid valve, type EV310B 3 Applications It is recommended to use a filter in front of the valve. Recommended filter 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/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 (chalk / lime stone...
