　　HYDAC valves may be used generally only in specific viscosity ranges, as in

　　zzNBR: from -30°C to +100°C (solenoid

　　solenoid valves - 20°C)

　　zzFPM: 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:

　　zzbrittle fracture of steel at low temperatures
