流量閥程序幾乎涵蓋影響液壓所需流量的所有功能。

6. VISCOSITY
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
ct on the used materials in the valve, e.g. their mech. strength. General
ly, the maximum temperature depends primarily on the sealing materials. H
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
