Other influences of temperature:
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
primarily on the sealing materials.
HYDAC defines here:  z NBR: from -30°C to +60°C
(sometimes up to +100°C)
There are also deep temperature valves
(TT), where the seals are specially
designed for low temperatures.
The HYDAC pressure valve programme encompasses practically all pressure control
functions which are used in hydraulics. Pressure valves influence the system
