Recommended viscosity Modular Valves Instructions for use
Normal working hours are recommended viscosity :15 - 400cSt.
If the valve back to the oil damper, the viscosity range must be 15-200cSt.
Use any of the following hydraulic fluid
Petroleum oil: ISO VG32 or VG46 oil equivalent of oil.
Synthetic solution: phosphate ester fluid or liquid polyhydric alcohol esters. When phosphate ester fluids, use a special fluorine rubber seal.
Aqueous solution: the use of water - glycol solution.
Working oil temperature
Continuous working temperature of the oil is -15 - +70 ℃.
Hydraulic oil pollution should be controlled, otherwise it will cause damage or shorten the life of the valve.
Please ensure that pollution degree NAS 1638-11 level, with 25um or more sophisticated line filter.
All the stud plate screwed into the basis of the provisions, the floor surface or pipe mounting plate screw holes.
According to the hydraulic circuit, stacked stacking valve or solenoid valve, fitted with O-ring to the mounting surface toward the base plate.
Superimposed valve inserted in the bolt, make sure that the empty stack valve arrangement is correct, its modular valves at both ends.
Screw on the nut on the bolt with specified torque tighten the nut, after commissioning, shall be within the specified torque re-tighten the nut,
In order to achieve a sufficient preload.
Pressure adjustment, loosen lock nut and slowly turn the handle clockwise as the pressure increases, the adjustment is completed do not forget to tighten the nut.
