M- SEW C X / 0 / EX00 -DC-5 Hd DESCRIION OF FUNCION Operated check valve type SEW, are solenoid operated directional ball valves. hey control start stop and direction of oil flow. he valves basically consist of the housing (), one solenoid () seat-valve unit (), hardened steel ball (). he force of the solenoid () acts via the lever () on the check () and on the control push (). he filter in alimentation protect the check valve from to much clog. he spring (9) lock the check on the valve seat in neutral position from the solenoid () in work position. VALVE / : Symbol U valve with check : - neutral position : flow from to A, locked without leakage. - work position : flow from A to, locked without leakage. Symbol C valve with checks - neutral position: flow from A to, locked without leakage - work position: flow from to A, locked without leakage. VALVE / : Symbol D : / valve symbol U with check and with plate. A 9 Symbol Y : / valve symbol C with checks and with plate. Siège Social:, Rue Nourissat B..0 F-000 DIJON Cedex

2 GENERALIY Direct curent solenoid () its mechanical impact strength is approved by the CENELEC for explosion proof equipment. Insulation to I, it can work in tropical climates. Direct curent solenoid has the advantages of : - slow movement of the control spool. - energized maintenance of the control valve in intermediary position, is not detrimental to the solenoid. he solenoid housing can be oriented in steps of 90 on hydraulic valve. ELECRIC CONNECION JUNCION IN BOX FOR GROU I AND IIC he terminal box () can be oriented in steps of 5 on the solenoid housing (). he electrical connector on the outlet terminal box () can be arranged horizontally (on terminal box ) or vertically (on cover ) suitable for cable gland. he execution H is recommended for easy access to the terminal strip. JUNCION ON FEMALE AED FLANGE FOR GROU II ONLY. Connection with threaded rigid conduit approved in group II only. Seal integrated in the housing. Earth connection (5). he lead wire length normally supplied is.5 meter. Active lead wires (). Earth lead wire (). One earth connection (5) is available inside or outside the terminal box.
