Filtration and the associated particle size

 on the electrical current. An additional function is the maximum pressure protection.
surge and very hot temperatures can
result in extreme cases to failure of the
(sometimes up to +100°C)
There are also deep temperature valves
(TT), where the seals are specially
designed for low temperatures.
Other influences of temperature:
z brittle fracture of steel at low temperatures
z NBR: from -30°C to +60°C
hydraulic system when these particles
are accumulated in critical areas.
8. NOMINAL TENSION AND VOLTAGE
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
These spool valves are available in direct acting or pilot-operated design
The ambient temperature has a direct
e.g. their mech. strength. Generally,
the maximum temperature depends
primarily on the sealing materials.
HYDAC defines here:
valves which control the pressure of the consumer depending
in the voltage range of +/- 15% of
nominal voltage at max. 60 ° ambient
temperature. The combination of steady
effect on the used materials in the valve,
immediate failure of the parts in the
HYDAC proportional pressure reducing valves are continuously adjustable
solenoid. Therefore always a good heat
dissipation and voltage level has to be assured.
In solenoid valves coils are used
which are designed to operate safely
z FPM: from -20°C to +80°C
z relaxation of springs made of spring
steel at higher temperatures
z fusing of coils at continous operation
under high current and at high temperatures
