Data sheet Solenoid valves, EVUL Ordering coils Special note for R290: The EVUL coil (IP65/67) is validated in accordance to ISO 549, IEC 605 (ref. IEC/EN 60079-5). Ignition risk is evaluated in accordance to ISO 549 and IEC 605 (ref. IEC/EN 60079-5). See safety note at the bottom of this page. Please make sure that there is no spark, arc on the spade connection during the application. If coils are below IPx5, they must be protected against ultraviolet, moisture and major impact, especially the connection of coils. Always Install a fuse ahead of the coil: rated current: two times of rated current, time lag: medium, to avoid short circuit. The coil used in an area of not more than pollution degree 2. Follow the installation guide to mount the coil correctly, and apply o-ring for sealing to prevent moisture penetrating inside the coil.

Data sheet Solenoid valves, EVUL Design and material specifications 4 5 6 A 0 7 8 9 2 Danfoss 2_000A No. Description Material Bi-metallic tube Stainless steel / Cu 2 Bi-metallic tube Stainless steel / Cu Flange Stainless steel 4 Armature tube Stainless steel 5 Return spring Spring wire stainless No. Description Material 6 Armature Stainless steel 7 Pilot plate Thermoplast 8 Seat plate Teflon 9 Piston Brass 0 Inlet filter Stainless steel / brass Function Servo operated EVUL 8 are servo operated piston solenoid valves. The servo piston principle results in a fast operating and compact valve that is able to open against a high differential pressure. The valve closes rather soft, because the pilot system does not fully close before the main orifice has closed. This minimizes liquid hammer. When the coil is currentless, the main orifice, seat plate (8) and pilot orifice (on the pilot plate (7)) are closed. The pilot orifice and main orifice are held closed by the armature spring force and the differential pressure between inlet and outlet sides. When current is applied to the coil, the armature (6) is drawn up into the magnetic field and thus lifts the pilot plate (7) and opens for the pilot orifice so that the de-energising of the servo chamber (A) starts and the pressure is relieved to the level of the outlet side. As the inlet pressure that acts on the bottom of the piston (9) now is higher than the pressure in the servo chamber (A), the piston is moved upwards and lifts both the pilot plate (7) and the seat plate (8). When the seat plate is lifted, the main orifice opens for full flow. Therefore a minimum differential pressure of 0.02 bar is necessary to open the valve and keep it open. When the current to the coil is switched off, the spring (5) forces the armature (9) down towards the pilot plate (7). The pressure in the servo chamber (A) increases and the piston will no longer be able to hold the seat plate (8) in lifted position, by which the main orifice closes. The armature (6) continues its downwards movement until the pilot orifice on the pilot plate (7) is fully closed. Note: Danfoss recommends that a suitable filter or filter drier (max. size of 40 50 µm) is installed ahead of each solenoid valve to keep scale, solder material and other foreign dirt and particles out of the valve. Note: By using the valve for oil return application - please contact Danfoss. Danfoss DCS (az) 207.2 DKRCC.PD.BD0.C8.02 29
