DIRCIONL CONROL ydrulic Fluids ype of Fluids etroleum se Oils ynthetic Fluids 1) Wter Contining Fluids Remrks Use fluids equivlent to IO V32 or V46. Use phosphte ester or polyol ester type. When phosphte ester type fluid is to e used, prefix F- to the model numer ecuse specil sel (fluororuer) will e used. Use wter-glycol fluids or W/O emulsion type fluids. Notes 1: Not pplicle with -D nd -D series vlves. 2: For two types of mnully operted directionl vlves, DM- 06 nd DM- 10, only petroleum se oils 06X 10X nd polyol ester type fluids re ville. 3: Wter-glycol fluids cnnot e used for two types of solenoid operted poppet type two-wy vlves; CD- 03 nd CD-03 types. 4: For use with hydrulic fluids other thn those listed ove, plese consult your Yuken representtives is dvnce. 2.
