which are designed to operate safely
in the voltage range of +/- 15% of
nominal voltage at max. 60 ° ambient
temperature. The combination of steady
surge and very hot temperatures can
sealing materials. HYDAC defines here:
z NBR: from -30°C to +100°C
immediate failure of the parts in the
hydraulic system when these particles
are accumulated in critical areas.
8. NOMINAL TENSION AND VOLTAGE
(solenoid valves - 20°C)
In solenoid valves coils are used
Filtration and the associated particle size
range of 10 mm2 /s to 420 mm2/ s.
7.CONTAMINATION LEVEL (FILTRATION)
HYDAC manually actuated directional valves are poppett or spool valves which
5. MEDIA OPERATIONG TEMPERATURE RANGE
Like the ambient temperature the media
temp. range has a direct effect on the
used materials in the valve, e.g. their
mech. strength. Generally, the maximum
z FPM: from -20°C to +120°C
(all other influences see point 4)
6. VISCOSITY
HYDAC valves may be used generally
only in specific viscosity ranges, as in
too thin or thick liquids, the assured
features can not be fulfilled. These
viscosities are also different for the
different valves, but in average in the
temperature depends primarily on the
of contaminants in the hydraulic oil is
the most important point in the operation
of a hydraulic system. Exceeding the
specified particle size in the filtration
classes 21/19/16 to 18/16/13 may cause
result in extreme cases to failure of the
solenoid. Therefore always a good heat
dissipation and voltage level has to be assured
