value also varies from valve to valve.

3. TYPE OF HYDRAULIC FLUID

The type of operating fluid is closely 

linked to its viscosity. HYDAC can only 

the depending datasheet in detail.

These conditions are:

1. Pressure

At ths flow it is still reasonable to operate 

the valve. An operation above this value    

4. Ambient temperature range

will boost the power dissipation. This 

maximum pressure at which it can be 

operated without risk to the environment 

and life. For this value, we assume the 

warranty, as we have demonstrated in 

tests. It varies from valve to valve.

2. FLOW RATE

Each valve is designed for a certain 

maximum flow - due to its nominal size. 

5. Media operating temperature range

6. Viscosity of the fluid

recommend hydraulic fluids according to 

DIN 51524 Part 1 and 2. For these fluids 

the function of the valves is warranted.

2. Flow rate

3. Type of hydraulic fluid

7. Contamination level (filtration) of the 

operating fluid

8. Nominal current and voltage 

(proportional and solenoid operated valves) 

Each valve is designed for a certain 

could be used in hydraulics.

These conditions are depending on the 

corresponding valve and described on 

HYDAC hydraulically actuated directional valves are seat or piston spool valves which 

In general there are different conditions 

existing under which HYDAC valves
