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

　　流量閥通過機械或液壓改變節流閥橫截面來影響系統中的流量。 HYDAC在這一領域提供

　　手動和液壓控制的閥門。Like the ambient temperature the media temp. range has a direct effe

　　YDAC defines here:

　　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
