Fluid Cleanliness Mounting Bolt Kits Proper fluid condition is essential for long and satisfactory life For KBS*DG4V-3 of hydraulic components and systems. Hydraulic fluid must BK02-156493M (metric) have the correct balance of cleanliness, materials and addi- tives for protection against wear of components, elevated BK590716 (inch) viscosity and inclusion of air. If not using Eaton recommended bolt kits, bolts used should be to ISO 898, 12.9 or better. The following recommendations are based on ISO cleanli- ness levels at 2 μm, 5 μm and 15 μm. For products in this Seal Kits catalog the recommended level is: KBS*DG4V-3.....6027549-001

The products will be refurbished as necessary and retested Hydraulic Fluids to specification before return. Field repair is restricted to the replacement of the seals. Materials and seals used in these valves are compatible with antiwear hydraulic oils, and non-alkyl-based phosphate esters. The extreme operating viscosity range is 500 to 13 cSt (2270 to 70 SUS) but the recommended running range is 54 to 13 cSt (245 to 70 SUS).
Installation The proportional valves in this catalog can be mounted in any attitude, but it may be necessary in certain demanding appli- cations, to ensure that the solenoids are kept full of hydraulic fluid. Good installation practice dictates that the tank port and any drain port are piped so as to keep the valves full of fluid once the system start-up has been completed.
