.WRCE.../P RE 29137/08.13
Set-up, function and section: Type 2WRCE
Valves of type 2WRCE...-2X/P... are 2-stage high-response valves.
They control the quantity and direction of a flow and are
mainly used in control loops.
Set-up
They consist of the following assemblies:
– The pilot control valve (1) as 1-stage proportional valve (pi-
lot), with two solenoids as electro-mechanical converters
and a piston that is connected to the integrated pilot elec-
tronics via electrical feedback (6.2).
– The second stage (2) for flow control.
– An inductive position transducer (3) the core (4) of which is
attached to the piston (5) of the second stage.
– And integrated control electronics (6.1).
Function
The integrated electronics (OBE) compares command and actu-
al values and the solenoids of the pilot control valve are actuat-
ed with a proportional current according to the control deviation.
The pilot control valve takes a proportionally controlled po-
sition and controls the flow in and out of the control cham-
bers A (7) and B (8) that actuate the main spool (5) through
the closed valve control loop up to 0 control deviation.
This means that the stroke of the main spool is regulated pro-
portionally to the command value. It must be noted that the
flow also depends on the valve pressure drop.
Valve particularities
The flow can pass through the valve from A to B or from B to A.
The seat piston closes or opens at 5% of the command value.
At lower command values, the valve control loop attempts to
guide the piston and thus presses it onto the seat at full pilot
pressure and blocks the connection in a leak-free way.
The specified valve dynamics only apply to the control area
of the valve. At command value steps from the seat to lower
opening values, additional delay times occur.
The opening point of 5% (= 0.5 V or 0.5 mA) is set at the factory.
Due to the internal setting of the pilot control valve, the pi-
lot pressure is connected to control chamber B (8) in case of
a power failure, i.e. the main stage is closed.
The control electronics feature an offset setting to compen-
sate pilot trimming.
Due to differences in diameter in the seat range, the pistons
are statically not pressure-compensated. To compensate
the force differential, 6%/22% of the system pressure at pis-
ton S...L/S...R is required as pilot pressure. With reserves for
flow force and dynamics, this defines the recommended mini-
mum pilot pressure.

Preferably, port B is to be connected to the actuator.

Set-up, function and section: Type 3WRCE
1)
Valves of type 3WRCE...-2X/P... are 2-stage high-response valves.
They control the quantity and direction of a flow and are
mainly used in control loops.
Set-up
They consist of the following assemblies:
– The pilot control valve (1) as 1-stage proportional valve (pi-
lot), with two solenoids as electro-mechanical converters
and a piston that is connected to the integrated pilot elec-
tronics via electrical feedback (6.2).
– The second stage (2) for flow control.
– An inductive position transducer (3) the core (4) of which is
attached to the piston (5) of the second stage.
– And integrated control electronics (6.1).
Function
The integrated electronics (OBE) compares command and
actual values and the solenoids of the pilot control valve are
actuated with a proportional current according to the con-
trol deviation.
The pilot control valve takes a proportionally controlled po-
sition and controls the flow in and out of the control cham-
bers A (7) and B (8) that actuate the main spool (5) through
the closed valve control loop up to 0 control deviation.
This means that the stroke of the main spool is regulated pro-
portionally to the command value. It must be noted that the
flow also depends on the valve pressure drop.
Valve particularities
The opening point of 0% (V piston) is set at the factory.
Due to the internal setting of the pilot control valve, the pi-
lot pressure is connected to control chamber B (8) in case of
a power failure, i.e. the main stage is opened from A to T or
the connection P to A is closed.
The spring behind the main spool moves it into position
so that P to A is closed if no pressure is applied (e.g. pri-
or to installation, before the pressures are reapplied after
tool change).
The control electronics feature an offset setting to compen-
sate pilot trimming.

Command and actual value have the same polarity. In case of failure of the fuse "1A fast", the actual value may temporarily
also be measured between F and B.
Notice: Do not use electrical signals provided via control electronics (e.g. actual value) for switching safety-relevant
machine functions (see also EN ISO 13849 "Safety of machinery – safety-related parts of control systems").
