Solenoid valve, type EV310A 2 Functions 2.1 Function, NC / NC MAN Coil voltage disconnected (closed): When the voltage to the coil (4) is disconnected, the armature (2) with the valve plates (3) is pressed down by the closing spring (1) and closes the connection between P and A. At the same time, the connection between gates 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 (2) with the valve plates (3) is lifted and closes the connection between A and R....

Solenoid valve, type EV310A 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...
