Product description
Valves of type 3WRCE are pilot-operated, 3-stage directional high-response cartridge valves. They control the quantity and direction of a flow and are mainly used in control loops.
Set-up
The valves consist of the following assemblies:
- 2-stage pilot control valve (1)
- with dry torque motor
- low-friction nozzle flapper plate amplifier
- mechanical feedback of the control spool position
- Main stage (2) for flow control
- An inductive position transducer (3) the core (4) of which is attached to the main control spool (5) of the third stage
- Integrated electronics (6).
Function
The integrated electronics compares command and actual values and the torque motor of the pilot control valve is actuated with a proportional current according
to the control deviation.
The pilot control valve (1) takes a proportionally controlled position and controls the flow in and out of the control chambers A (7) and B (8) that actuate the main control spool (5) through the closed valve control loop up to 0 control deviation.
This means that the stroke of the main control spool (5) is regulated proportionally to the command value. It must be noted that the flow also depends on the valve pressure drop.
Valve features
The opening point of 0% (symbol V) is set at the factory. Upon replacement of the pilot control valve (1) or the control integrated electronics (6), the opening point can be readjusted using the zero adjustment potentiometer R316 (accessible via a plug screw).
During the exchange, no settings must be made at the control electronics (= controller or control electronics) and the pilot control valve (1), except for the zero adjustment at the position transducer.
At the pilot control valve (1), only the filter element may be exchanged. The pilot control valve (1) is trimmed so that the pilot pressure is connected to control chamber B (8) in case of a power failure, i.e. the main stage opens from A to T and/or closes the connection from P to A.
The spring behind the main control spool (5) moves it into position so that P to A is closed if no pressure is applied (e.g. prior to installation, before the pressures are reapplied after tool change).
The integrated electronics (6) features an offset to compensate the trimming (pilot trimming) of the pilot control valve (1).
Notice:
Version "3WRCE" is not recommended for new applications. If version "3WRCE" is used, ports A and P have to be exchanged. Upon request.

Power supply
- +24 VDC ±6 V; full bridge rectification with smoothing capacitor 2200 µF = Imax = 230 mA
- ±15 VDC ±0.45 V; stabilized and smoothened; Imax = 180 mA
Command value
- 0 … +10 mA / ±10 mA → input resistance 100 Ω
Actual value
- 0.5 mA … +10 mA / ±10 mA → maximum load resistance 1 kΩ
Notices:
- Do not connect PE if the valve has already been grounded via the system.
- Command value and actual value have the same polarity.
- Electrical signals provided via control electronics (e.g. actual value) must not be used to switch off safety-relevant machine functions.
- Mating connectors, separate order, see "Accessories" and datasheet 08006.
Nominal command value range
0 … ±10 V; 0 … ±10 mA (0 … ±100 %)
- In case of a slow command value modification from 0 V ... ±10 V, the actual value follows the command value within ±0.1 V.
- With command values of more than ±10 V, the actual value will follow to approx. ±13 V
- At a command value step to +10 V, the actual value can temporarily reach values of up to approx. +10.5 V.
Effect of the control:
A positive signal at pin D and a reference potential at pin E results in Flow P → A
