TECHNICAL DATA

VALVES INSTALLATION Hydrover product H
It is reccomended to follow these steps:
• inspect the sub-plate to ensure that it is in good conditions and no external contaminant is present Manifolds 1
• check that O-Rings are intact and correctly positioned
• don’t tighten screws or connectors more than the maximum torque specified in the catalogue Valves for hydraulic motors 4 14 Series
Multi ports manifolds 6 16 Series
INLET VOLTAGE
To obtain correct operation and long life of coils it is necessary that the operating voltage fluctuations do not exceed +5% Inline valves 7 17 Series
-10 % of nominal voltage.

WORKING DUTY
The working duty ED of a coil is the ratio between energized time ti and full cycle time tc where tc=ti+tr and tr = de-energized
time. Hydrover product H

HYDRAULIC FLUID
It must have physical lubricating and chemical properties suitable for use in hydraulic systems such as, for example: Flangeable elements for Bosch Rexroth ED bankable valves 9 49 Series
• MINERAL OIL FLUIDS HL (DIN 51524 part1)
• MINERAL OIL FLUIDS HLP (DIN 51524 part2)
For use of environmentally acceptable fluids (vegetable or polyglycol base) please consult LC Oleodinamica. Hydrover product H
Viscosity class: with ISO-DIN, the viscosity class is expressed by ISO-VG (no.); the no. Indicates the average kinematic
viscosity at 40°C in mm2/s or centiStoks (cSt). Cetop 5 products 5

CONTAMINATION – FILTRATION
• GENERAL INFORMATION: Manufacturers and users of hydraulic equipment admit that contamination is the most Load sensing modular Cetop 5 subplates for parallel circuits 2 52 Series
likely cause of malfunction or failure in hydraulic systems and reduces security and reliability of components and
systems. Metal particles flowing throughout the circuit scratch moving surfaces so that contamination level, if not Cetop 5 subplates 6 56 Series
controlled, increases very rapidly. It is strongly recomended to mantain contamination level at least at nominal values Cetop 5 modular valves 9
shown below, choosing adequate filtration products. 59 Series
• FILTRATION RATIO BETAx: It’s the ratio between the number of particles before and after the filter with diameter
larger than X micron.
• ABSOLUTE FILTRATION RATIO ISO 4572: It’s the diameter X of the largest particle with BETAx≥ 75. Hydrover product H
• CONTAMINATION CLASS ISO 4406: it’s expressed by 3 scale numbers representing respectively: the number of Accessories 6
particles equal to or larger than 4 micron (c); the number of particles equal to or larger than 6 micron (c); the number
of particles equal to or larger than 14 micron(c), contained in 1 ml of fluid. Electronic controls 1 61 Series
• CONTAMINATION CLASS NAS 1638: It’s expressed by one scale numbers representing the number of particles of
different size ranges contained in 100 ml of fluid.
