Data sheet | Solenoid valves, type EV220B 65 - EV220B 100 Function 1. Armature 2. Closing spring in pilot system 3. Valve plate 4. Pilot orifice 5. Servo piston 6. Main orifice 7. Coil 8. Equalizing orifice Coil voltage disconnected (closed): When the voltage is disconnected, the valve plate (3) is pressed down against the pilot orifice (4) by the pilot system’s closing spring (2). The pressure across the servo piston (5) is built up via the equalizing orifice (8). The servo piston closes the main orifice (6) as soon as the pressure across the piston is equivalent to the inlet pressure. The...

Data sheet | Solenoid valves, type EV220B 65 - EV220B 100 Periodic maintenance/inspection Maintenance/Inspection every 6 to 12 months recommended. Before starting maintenance/inspection be sure: - Coil is not energized when removed from the armature tube. - System/solenoid valve is not pressurerised. Eventually close ball valves on each side of the valve. – Be sure any pumps one the upstream (inlet supply) will not be energized or a pressure sensor or switch will not start the pump. - After cleaning and service, eventually with Danfoss spare part kit, it is recommended to lubricate piston...
