Solenoid valve, Type EV220A 2 Functions 2.1 Function, NC Coil voltage disconnected When voltage is disconnected, the armature spring (2) presses the armature (3) down against the pilot orifice (4). Pressure builds up over the diaphragm (5) via the equalizing orifice (7). The diaphragm closes the main orifice (6) as soon as the pressure over the diaphragm equals the inlet pressure. The valve stays closed for as long as voltage remains disconnected.

Solenoid valve, Type EV220A 3 Applications It is recommended to use a filter in front of the valve. Recommended filter 50 mesh (297 microns). Danfoss 32U1460 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.
