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
