Function, section
Valve types FES(E) are pilot operated 2-way proportional throt-
tle valves for block installation for the infinitely variable control
of a flow.
Technical structure:
The valve consists of four main assemblies:
– Cover (1) with mounting face for pilot oil ports.
– Main valve (2) with orifice spool (3).
– Pilot valve (4) with proportional solenoid (5).
– Integrated control electronics (6) (not provided for type FES)
with position transducer (7).
General function:
– Command value-related closed-loop position control of
orifice spool (3) and therefore defined opening of orifice (8).
– The flow depends on the
Δp across orifice (8) and the posi-
tion of orifice spool (3).
– Actual value acquisition of the position of orifice spool (3) by
position transducer (7); command/actual value comparison
in electronics (6); deviations are conditioned and passed on
to proportional solenoid (5) of pilot valve (4) in the form of a
control output for correcting the position of orifice spool (3).
– Area ratio of area (14) to area (15) = 2 : 1 for
size 25; 32; 40, and 1.6 : 1 for size 50; 63.
– Direction of flow A
→ B (connect X with A);
direction of flow B
→ A (connect X with B);
external pilot oil supply via X possible.
– When the enable is withdrawn, orifice spool (3) moves onto
valve seat (9) and closes the direction of flow A
↔ B leak-
free. Spool seal (11) ensures the leak-free isolation of port B
from control chamber (12); with internal pilot oil supply, take
leakage oil from X via the pilot valve to Y into account!
– Orifice spool position is already controlled at a command
value of 0 V or 4 mA, with orifice (8) still being in the positive
overlap position.
Function of opening orifice spool:
(Assumption: flow A
→ B and A connected with X)
• Proportional solenoid (5) shifts pilot spool (4.1) against
spring (13) and opens the connection between control
chamber (12) and Y; the pressure in control chamber (12)
is reduced and orifice spool (3) moved to the direction of
opening by the pressure in A that acts on area (15) plus the
pressure in B that acts on the annulus area (16).
Function of closing orifice spool:
(Assumption: flow A
→ B and A connected with X)
• Current reduced in proportional solenoid (5); spring (13)
shifts pilot spool (4.1) against the proportional solenoid and
opens the connection between X and control chamber (12);
the pressure acting on area (14) plus spring force (10) shift
orifice spool (3) in the closing direction.
Flow control function:
• In conjunction with a pressure compensator, can be used for
the pressure-compensated control of a flow.
Failure of supply voltage:
• The integrated electronics de-energises the solenoid in the
event of a supply voltage failure or cable break in position
transducer (7).
• The spool is shifted to valve seat (9) by the pressure applied
to pilot port X plus spring force (10) and blocks the flow
A
→ B.
Caution: A voltage supply failure results in a sudden standstill of the controlled axis.
Accelerations that can occur in conjunction with this can cause damage to machines!

Function
1. Making operation/disturbance characteristic:
After the supply voltage of 24 V was applied, the electronics is
ready for operation, if the following conditions are fulfilled:
– Operating voltage
U
O
> 18 VDC
– The internal ± 7.5 V supply voltage is symmetrical
– The connection to the position transducer is not interrupted.
– The command value cable is not interrupted
(only with 4 mA to 20 mA interface)
If one of these conditions is not fulfilled, the controller and the
output stage are blocked and the signal “ready for operation” is
set to < 8 V.
2. Normal operation
When the enable is inactive (< 8 V) and an optional command
value is fed forward (0 to 10V or 4 to 20 mA) the orifice spool
is in the seated position and blocks the flow from A to B.
By applying a voltage > 10 V to the enable, the position con
-
troller for the orifice spool and the output stage for the pilot
valve are switched on. At the same time, the position control-
ler (PID) compares the actual value of the orifice spool position

the output stage, which changes the solenoid current until the
orifice spool position corresponds to the command value.
The actual value of the orifice spool position is sensed by an in-

by the demodulator and fed back to the PID-controller.
