8. NOMINAL TENSION AND VOLTAGE
In solenoid valves coils are used
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
z FPM: from -20°C to +80°C
(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 NBR: from -30°C to +100°C
immediate failure of the parts in the
hydraulic system when these particles
z brittle fracture of steel at low
temperatures
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

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
range of 10 mm2 /s to 420 mm2/ s.
7. CONTAMINATION LEVEL
(FILTRATION)
Filtration and the associated particle size
of contaminants in the hydraulic oil is
the most important point in the operation
result in extreme cases to failure of the
solenoid. Therefore always a good heat
dissipation and voltage level has to be
Like the ambient temperature the media

HYDAC direct acting pressure relief valves are spring-loaded cone-
or ball-type poppet valves which limit the pressure in hydraulic systems out of safety reasons.
(solenoid valves - 20°C)
A leakage-free securing of consumers and systems is enabled.
Different pressure ranges enable an optimum system adjustment.
The direct acting pressure relief valve DB06A is a leakage-free poppet
valve used for limiting the inlet pressure by opening the outlet
against spring force. Cavity UNF 9/16-18. Qmax = 15 l/min Pmax = 350 bar

used materials in the valve, e.g. their
mech. strength. Generally, the maximum
temperature depends primarily on the
sealing materials. HYDAC defines here:
