In multiple active industries, we are the foremost organization for manufacturing and supplying a wide assortment of Modular Valves. The offered valves are designed and assembled in accordance with the international industrial standards, made up by finest quality component under the supervision of our skilled experts. These valves are demanded for regulating, directing or controlling the flow of a fluid by closing, opening, or partially obstructing passageways. These Modular Valves are available in several models and capacity ratings at minimum industrial price range.
Long operational life
YUKEN's Modular Valves are stack type valves, and require no piping. They not only rationalize system build, but they also meet the technical requirements for a variety of hydraulic systems. Stacking systems is a new era in hydraulics. The valves have standardized mounting surface conforming to ISO 4401 and optimum thickness for each size. Any hydraulic circuits can be easily composed by stacking the valves with mounting bolts. The valves can be used widely for hydraulic systems for various industries such as machine tool, special purpose machines, ships and steel mill equipment. High Pressure, High Flow Rate Modular Valves 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 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 Hydraulic Fluids. Fluid Types Any type of hydraulic fluid, listed in the table below can be used. Petroleum base oil Use fluids equivalent to ISO VG 32 or VG 46. Synthetic fluids Use phosphate ester or polyol ester fluid. When phosphate ester fluid is to be used, prefix to the model number because a special seal (fluoro rubber) 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 +70 0C 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 mm or finer line filter.
