1 3 SERIES General Information Mounting Surface : ISO 44-C--4-, CETO-, N-DO Up to Ma (363 SI), 7 L /min (8. U.S.GM) ub. EC-43 MODULR VLVES The modular valves are functional elements with which a hydraulic system can be composed and built easily by stacking them with the mounting bolts. Therefore, no piping is required for the manufacture of the hydraulic systems. Yuken's 3 Series Modular Valves are widely used to compose the hydraulic systems for the various industrial and marine equipment including machine tools, special purpose machines, steel mill equipment and ships. The valves have standardized mounting surface conforming to ISO 44-C--4- and optimum thickness for the stacking.

4 3 SERIES Instructions MODULR VLVES Instructions Caution in the selection of valves and circuit designing The selection of modular valves, to suit a particular function or hydraulic circuit, are made in exactly the same way as conventional valves, taking into account of the flow and pressure of each valve to be used. In some cases, the stacking system may be restricted, so please refer to the following instructions for stacking sequence. lease note, that when designing a system using modular stacking valves, due consideration should be given to working space for future maintenance. Stacking sequence when using reducing valves (for "" or "" line) and pilot operated check valves. ecause reducing valves are spool type, there is an internal leakage. In the stacking sequence shown in the drawing left (incorrect), the cylinder moves due to leakage through the pilot pressure line. Consequently, retaining the position of the cylinder using a pilot operated check valve becomes impossible. The stacking sequence shown in the drawing right (correct) is required in order to retain the cylinder position. Solenoid Operated Directional Valve ilot Operated Check Valve (for "&-Lines") Reducing Valve (for "-Line") (Incorrect) (Correct) T T Stacking sequence when using reducing valves (for "" or "" line) and throttle and check valves (for metreout). In to T flow in the drawing left (incorrect), pressure is generated at part with a throttle effect of the throttle and check valve. Depending upon the pressure so generated, the reducing valve may perform a pressure reducing function which causes a shortage of output power of the cylinder and spoils the smooth operation of the cylinder. Therefore, stacking sequence in the drawing right (correct) is required in this combination. Solenoid Operated Directional Valve Throttle and Check Valve (for "&-Lines, Metre-out") Reducing Valve (for "-Line") (Incorrect) (Correct) T T Stacking sequence when using pilot operated check valves and throttle and check valves (metre-out). In to T flow in the drawing left (incorrect), pressure is generated at part with a throttle effect of the throttle and check valve. The pressure so generated acts to shut the pilot operated check valve and eventually creates an open and shut operation of the valve repeatedly which may cause the cylinder to have a knocking effect (the same effect will occur in the case of to T flow). Therefore, the stacking sequence in the drawing right (correct) is required in this combination.

Hydraulic luids luid Types ny type of hydraulic fluid listed in the table below can be used. etroleum base oils Synthetic fluids Water containing fluids Use fluids equivalent to ISO VG 3 or VG 46. Use phosphate ester or polyol ester fluid. When phosphate ester fluid is used, prefix "-" to the model number because the special seals (fluororubber) are required to be used. Use water-glycol fluid. Note: or use with hydraulic fluids other than those listed above, please consult your Yuken representatives in advance. Recommended Viscosity and Temperatures lways be sure to use hydraulic fluids within the stipulated conditions shown below: Viscosity: to 4 mm /s (77 to 8 SSU), Temperature: - to +7 C ( to 6 ) Control of Contamination Due caution must be paid to maintaining control over contamination of the hydraulic fluids which may otherwise lead to breakdowns and shorten the life of the valve. lease maintain the degree of contamination within NS 638-Grade. Use μm or finer line filter. ase lates and Sub-lates When mounting the modular valves, use base plates and sub-plates specified below. If these base plates and the subplates are not used, ensure that the mounting surface has a good machined finish. ase lates MMC-3-T- -/8/9 age 44 Sub-lates DSGM-3-4/8/9 or the details of Sub-late, see the following DSG-3 solenoid operated directional valve catalogues: Catalogue No. ub.
