1 High Pressure, High Flow Rate Features Installation and mounting space can be minimized. No special skill is required for assembly and any addition or alternation of the hydraulic circuit can be made quickly and easily. Problems such as oil-leaks, vibration and noise which may be caused by piping are minimized, increasing the reliability of the hydraulic system. Maintenance and system check-ups can be easily carried out as they are normally installed in stackable units Series Valve Size Max. Operating Pressure Max. Flow Number of Stack 01 Series 1/ (Note) 03 Series 3/ to 06 Series 3/ stacks Note: Solenoid operated directional vlave is included in the number of stack. Hydraulic Fluids. Fluid Types Any type of hydraulic fluid, listed in the table below can be used. Mounting Surface Mounting surface dimensions conform to ISO 4401 (Hydraulic fluid power four port directional control valves mounting surface) as listed in the table below. Name of Valve ISO Mtg. Surface Code No. 01 Series Modular Valve ISO 4401-AB-03-4-A 03 Series Modular Valve ISO 4401-AC-05-4-A 06 Series Modular Valve ISO 4401-AE-08-4-A Petroleum base oil Use fluids equivalent to ISO VG 32 or VG 46. Use phosphate ester or polyol ester fluid. When phosphate ester fluid is to be used, prefix F- to the Synthetic fluids model number because a special seal (fluororubber) will be used. Water containing fluids Use water-glycol fluid Note: For use with hydraulic fluids other than those listed above, please consult your Yuken representatives in advance. Recommended Viscosity and Temperatures Always be sure to use hydraulic fluids within the stipulated conditions shown below: Viscosity: 15 to 400cSt (75 to 1800SSU), Temperature :- 15 to C (5 to F) Control of Contamination Due caution must be given for maintaining control over contamination of the hydraulic fluids which may other wise lead to breakdowns and shorten the life of the valve. Please maintain the degree of contamination within NAS 1638-Grade 12. Use 25 µm or finer line filter. Stacking Example 03 Series 210

2 MODULAR VALVES 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 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 modular valves (for A or B line) and pilot operated check modular valves. Because 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. Stacking sequence when using reducing modular valves (for A or B line) and throttle and check modular valves (for metre-out) In B to T flow in the drawing left (incorrect), pressure is generated at part with a throttle effect of the throttle and check modular valve. Depending upon the pressure so generated, the reducing modular valve may perform a pressure reducing function which causes a shortage of output power from the cylinder and spoils the smooth operation of the cylinder. Therefore, stacking sequence in the drawing right (correct) is required in this combination. Stacking sequence when using pilot operated check modular valves and throttle and check modular valves (metre-out). In A to T flow in the drawing left (incorrect), pressure is generated at part with a throttle effect of the throttle and check modular valve. The pressure so generated acts to shut the pilot operated check modular 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 B to T flow). Therefore, the stacking sequence in the drawing right (correct) is required in this combination. Stacking sequence when using brake modular valves and throttle and check modular valves. In the drawing left (incorrect), pressure is generated at part (a load pressure and a back pressure from throttle effect). For structual reasons of the brake valve, the load pressure and back pressure act to open the vlave. Therefore, the setting pressure should be more than the pressure equal to the load pressure plus back pressure (Pa + Pb). If the setting pressure is less than Pa + Pb, the brake valve acts and brakes the movement of the acuator in operation, this eventually reduces the speed of the actuator. On the contrary, if the setting pressure is more than Pa + Pb, shock may occur when braking the actuator since the setting pressure is too high against the load pressure. Therefore, the stacking sequence in the drawing right (correct) is required in this combination. 211

3 Base Plates and Sub-Plates When mounting the modular valves, use base plates and subplates specified below. If these base plates and the sub-plates are not used, ensure that the mounting surface has a good machined finish. Modular Base Plates Sub-Plates Valve Series Model Numbers Page Model Numbers 01 Series MMC DSGM Series MMC-03-T DSGM Page * * * For the details of sub plates see page152 for 01 series &162 for 03 series. Assembly Assembly should be carried out in clean conditions and in accordance with the following procedure. Caution attention should be paid to ensure that the interface of the valves are clean and free from dirt or other foreign materials. Assembly Procedure : 1) Screw-in the four stud bolts, fully into the tapped holes on the mounting surface of the specified base plate, sub-plate or manifold. 2) Stack the modular valves and solenoid operated direc tional valves in accordance with the hydraulic circuit, place the O-ring inserted face on the base plate and make sure that the port arrangement of the modular valves are in t he correct position before stacking the valves using stud bolts. 3) Align both the end of the valves stacked. 4) Screw-in the four nuts onto the stud bolts and tighten with the specified torque. After the test run, be sure to re-tighten the nuts to a firm tightness within the specified torque. Mounting Bolts 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 to a firm tightness within the specified torque. Modular Bolt Kit Model Tightening torque Valve Numbers kgf-m Series 01 Series MBK Series MBK [Example] 03 Series Module Valves Pressure drop curves of the modular valves are those based on viscosity of 35cSt(160 SSU) and specific gravity of When using the modular valves in condition other than the above mentioned, find the appropriate valves referring to the following table and formula. For any other viscosity, multiply the factors in the table below. Viscocity Factor cst SSU For any other specific gravity (G'), the pressure drop ( P') may be obtained from the following formula.
