These conditions are depending on the 

corresponding valve and described on 

the depending datasheet in detail.

(solenoid valves - 20°C)

z FPM: from -20°C to +80°C 

Shut-off valves from HYDAC are poppet and spool valves for the controlled

designed for low temperatures.

Other influences of temperature:

z brittle fracture of steel at low 

temperatures

z relaxation of springs made of spring 

z NBR: from -30°C to +60°C 

steel at higher temperatures

z fusing of coils at continous operation 

under high current and at high 

temperatures

In general there are different conditions 

existing under which HYDAC valves 

could be used in hydraulics.

 opening or closing of lines and other hydraulic components.

the maximum temperature depends 

primarily on the sealing materials. 

HYDAC defines here:

(sometimes up to +100°C)

There are also deep temperature valves 

(TT), where the seals are specially 

 They control inlet, dischrage or outlet of hydraulic fluids.

The ambient temperature has a direct 

effect on the used materials in the valve, 

e.g. their mech. strength. Generally,
