Hydraulic oil Use a petroleum-based hydraulic uid equivalent to ISO VG to 8. Operate the unit in an environment where both the following conditions are satisfied: viscosity range from 5 to mm /s {cst} and oil temperature from 5 to 7 C. Note that the optimum viscosity range of the ow control valves is to 5 mm /s {cst}. Contamination of the hydraulic uid causes valve trouble and reduces the service life, so pay due attention to controlling contamination and ensure that it goes no higher than NAS contamination class. Installation and maintenance There is no restriction on the installation direction. Finish the face on which the valve is mounted to a surface roughness of.a or better and a flatness tolerance within. mm. Use an O-ring with a hardness of Hs9 for the valve's gasket unless otherwise speci ed. Connect the piping from the valve to the tank at a point lower than the tank oil level. Filters Use a line lter with a ltration accuracy of 5 μm or better. F-
