Product Parameters

 

Valves of type 4WRKE are 2-stage proportional directional valves.
They control the of flow direction and size.
The main stage is position-controlled so that the control spool
position is independent from flow forces also in the case of
bigger flows.
The valves mainly consist of the pilot control valve (1), the
housing (8), the main control spool (7), the covers (5 and 6),
the centering spring (4), the inductive position transducer (9)
and the pressure reducing valve (3).
If there is no input signal, the main control spool (7) will be
kept in the central position by the centering spring (4). Both
control chambers in the covers (5 and 6) are connected to the
tank via the valve control spool (2).
The main control spool (7) is connected to suitable control
electronics via the inductive position transducer (9). Both
the change of position of the main control spool (7) and the
change of the command value at the junction summing of the
amplifier create a differential voltage.
