1 2/2 Solenoid Operted Set Vlve, ISO Size 03 Q mx = 20 l/min (5.3 gpm), p mx = 315 r (4500 psi) Sndwich design, idirectionl lek-proof shutoff, direct cting, with EX-sfty sol. coil Vlve: With crtridge vlve, type EEX-W1C. Interfce to ISO De-energised closed Guided vlve spool nd poppet idirectionl lek-proof shutoff or flow Sndwich ody is zinc-phosphted Solenoid coil: o IEC/EN , IEC/EN , IEC/EN For equipment in Ctegory 2 (Zones 1 nd 2) Certificte of conformity: SEEF 02 EX 0199 X 1 Description II 2 G Ex e m IIC 4 G sndwich vlves re high performnce, 2/2 solenoid operted set vlves with size 03 interfce to ISO n EX-protected solenoid for explosive gs tmospheres (II 2 G) is used to provide electricl opertion of the crtridge. he min components of the vlves re sndwich ody (stck-mounting ody) nd the push-in 2/2 directionl set vlve crtridge (type EEX- W1C. ). he 2/2 solenoid operted crtridge set vlve is designed on the poppet/set principle, nd is therefore virtully lek-free in oth directions of flow (idirectionl set-vlve shut-off). hese sndwich vlves cn e supplied s de-energised-closed (see symols). hese 2/2 solenoid operted crtridge set vlve re predominntly used in certin moile nd industril pplictions where lek-tight shut-off functions re crucilly importnt. Exmples re where lods, tensions, or clmping forces must e held without lekge. he sndwich ody is zinc-phosphted. ll externl prts of the vlves re plted nd re thus suitle for use operting environments. he sndwich ody is seled t its mnifold side (the connections side) y mens of O-rings fitted in counterores.

Detiled performnce dt nd other hydrulic chrcteristics cn e found in the dt sheet for the respective 2/2 solenoid operted crtridge set vlve (series EEX-W1C. ) tht is fitted. See Relted dt sheets. ENION! he performnce figures in the dt sheet for the crtridge vlve refer just to the crtridge itself. ke into ccount the dditionl pressure drop in the ody into which it is fitted. 5 Instlltion informtion COMMISSIONING For short-circuit protection, ech solenoid must e preceded y fuse conforming to 588 or IEC269 with mximum rting of 2 (C) or 6 (DC). he solenoid coils must only e operted when they re fitted on the ssocited vlve. For more informtion on instlltion nd commissioning, plese refer to the operting instructions supplied with the solenoid coil. ENION! Rtings given in the operting instructions y ttention to the relevnt operting instructions! If in dout, the rtings in the operting instructions pply. ENION! Only qulified personnel with mechnicl skills my crry out ny mintennce work. Generlly, the only work tht should ever e undertken is to check, nd possily replce, the sels.
