1 6 SERIES General Information Mounting Surface : ISO -AE-8--A, CETOP-8, NPA-D6 Up to 5 MPa (363 PSI), 5 L /m in (3 U.S.GPM) Pub. EC- 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 6 Series Modular Valves are widely used to compose the hydraulic systems for the various industrial and marine equipment including machine tools, special purpose machines, presses, steel mill equipment and ships. The valves have standardized mounting surface conforming to ISO -AE-8--A and optimum thickness for the stacking.

3 6 SERIES Instructions 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. Please 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 "A" 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 Controlled Pilot Operated Directional Valve Pilot Operated Check Valve (for "A&-Lines") Reducing Valve (for "-Line") (Incorrect) (Correct) P T A P T A Stacking sequence when using reducing valves (for "A" or "" line) and throttle and check valves (for 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. Depending upon the pressure so gener-ated, 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 Controlled Pilot Operated Directional Valve Throttle and Check Valve (for "A&-Lines", Metre-out) Reducing Valve (for "-Line") (Incorrect) (Correct) P T A P T A Stacking sequence when using pilot operated check valves and throttle and check valves (metreout). In A 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.

Please refer to the Catalogue No. Pub. EC- for details. Hydraulic luids luid Types Any type of hydraulic fluid, listed in the table below can be used. Petroleum base oils Use fluids equivalent to ISO VG 3 or VG 6. Synthetic fluids 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. Water containing fluids Use water-glycol fluid. Note:or use with hy draulic fluids other than those listed above, please consult y our Yuken representatives in advance. Recommended Viscosity and Temperatures Always be sure to use hydraulic fluids within the stipulated conditions shown below: Viscosity: 5 to mm /s (77 to 8 SSU), Temperature: -5 to +7 C (5 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. Please maintain the degree of contamination within NAS 638-Grade. Use 5 µm or finer line filter. Sub-plates When mounting the modular valves, use sub-plates specified below. If these sub-plates are not used, ensure that the mounting surface has a good machined finish. Sub-plate : DHGM-6-5/58/59 Note: or the details of Sub-plate, see the following catalogues: Catalogue No. Pub. EC- Mounting olts 6 Series modular valves are mounted using stud bolts which are supplied in a kit form. When mounting, see the following table for tightening torque. After the test run, be sure to tighten again firmly within the specified torque. olt Kit Model Numbers Tightening torque Nm (in. lbs.) MK MK (3-53) No.
5 6 SERIES Assembly / Pressure Drop Assembly Assembly should be carried out in clean conditions and in accordance with the following procedure. Cautious attention should be paid to ensure that the interface of the valves are clean and free from dirt or other foreign materials. Assembly Procedure: ) Screw-in the six stud bolts, fully into the tapped holes on the mounting surface of the specified sub-plate or manifold. ) Referring to the circuit diagram, stack the modular valve and the solenoid controlled pilot operated directional valve. Take care to face their o-ring side to the sub-plate or manifold, put the stud bolts in position and be sure to check that the locating pins are at the pin holes. 3) Align both the end of the valves stacked. ) Screw-in the six nuts onto the stud bolts and tighten with the specified torque. After the test run, be sure to re-tighten the nuts firmly within the specified torque. SOL a AP SOL b Nut Stud olt Mounting olt Kits 3/ Solenoid Controlled Pilot Operated Directional Valve 6 Series Modular Valves CAUTION Keep all installation holes and surfaces clean. ailure to do this may cause fire due to oil leakage. efore installing the product, be sure that all specified bolts are tightened to the specified torque levels. Tightening to levels outside specifications may cause improper operation, damage, oil leakage, etc. [Example] 6 Series Modular Valves Pressure Drop Pressure drop curves of the modular valves are those based on viscosity of 35 mm /s (6 SSU) and specific gravity of.85. When using the modular valves in conditions other than the above mentioned, find the appropriate values referring to the following table and formula. or any other viscosity, multiply the factors in the table below. mm /s Viscosity SSU actor or any other specific gravity (G'), the pressure drop ( P') may be obtained from the following formula.
