The directional valve of the WE model is an electromagnetic coil-operated directional spool valve, and this valve can be used as an electromagnetic component. This valve controls the start, stop and direction of the fluid.
The basic structure of this directional valve consists of a housing, one or two electromagnets, a control spool and a return spring. In the power-off state, the control spool is held in the middle position or the initial position (except for version "O") by the return spring. When the electromagnet in the hydraulic oil is energized, the control spool moves from its rest position to the desired end position. In this way, the desired fluid direction can be issued according to the selected symbol.
After the electromagnet is turned off, the control spool will be pushed back to the middle position or the initial position (except for valves with "OF" device and valves without spring type "O").
The auxiliary operation can manually switch the valve when the magnet is not energized.
The hydraulic system must be properly ventilated to ensure normal function.
Without spring return "O" (only applicable to symbols A, C and D)
This model is a directional valve with two switching positions and two electromagnets without a device. The valve without spring return at the control spool has no definite initial position in the power-off state.
Without spring return, with device "OF" (only applicable to symbols A, C, and D)
This model is a directional valve with two switch positions, two electromagnets, and a device. The control spool is fixed in the corresponding switching position by the device. Therefore, during operation, there is no need to apply current to the electromagnets, which helps with energy-saving operation.
Model "73...A12" (soft switching behavior)
The combination of the control spool and the electromagnetic coil reduces the number of commutation strokes that occur when the valve opens or closes.
Compared with standard valves, the commutation stroke (measured as the acceleration value a) can be reduced by approximately 85%, depending on the model of the control spool (see "Acceleration value").
Note:
Pressure peaks in the drain lines connecting two or more valves may cause unexpected movement of the control spool in models with a device. It is recommended to lay separate return lines or install check valves in the drain lines.
Due to the design principle, internal leakage will occur in the valve, and the leakage amount will increase during the service life.
Throttle plug-in
According to the main working conditions, if the flow rate may exceed the performance limit of the valve during the switching process, a throttle plug-in will be required.

Pilot control valve (first stage) of type 4WRAP 6 W7.3X/G24…
The pilot control valve is a direct-acting proportional valve. The geometry of the control edges is optimized and can be used as the pilot control valve for the proportional directional valve model 4WRKE. The proportional solenoids are pressure-tight, hermetically sealed wet-pin DC coils with removable coils. They can convert the current into mechanical force in proportion. An increase in the current will cause a corresponding increase in the magnetic force of the coil. The set magnetic force of the coil will remain constant throughout the control stroke.
The pilot control valve mainly consists of a housing, proportional solenoids, a control spool, and springs. In the non-operating condition, both actuators are connected to the oil tank. If one of the two coils is energized, the magnetic force will move the control spool of the valve towards the spring. Once the overlap is exceeded, the connection between one of the two actuators and the oil tank will be blocked, and instead, it will be connected to the pressure chamber. The fluid flows from P to the control chamber of the main stage.
Valves of type 4WRKE are two-stage proportional directional valves. They control the flow direction and flow rate. The main stage is position-controlled, so that the position of the control spool will not be affected by the hydraulic force even under a large flow rate.
This type of valve mainly consists of a pilot control valve, a housing, a main control spool, a cover, a centering spring, an inductive position sensor, and a pressure reducing valve. If there is no input signal, the main control spool will be fixed in the center position by the centering spring. The two control chambers in the cover are connected to the oil tank through the control spool. The main control spool is connected to the appropriate control electronics through the inductive position sensor. Both the change in the position of the main control spool and the change in the control value at the summing point of the amplifier can generate a differential voltage. During the comparison of the control value and the theoretical value, the possible control deviation is determined by the electronics, and a current is applied to the proportional solenoid of the pilot control valve. The current will generate a force in the coil that continuously operates the control spool through the push rod. The flow rate activated through the control profile will cause the adjustment of the main control spool. The main control spool connected to the core of the inductive position sensor will keep moving until the theoretical value matches the control value. In the control state, the main control spool is in a force balance state and stays at this control position. The stroke of the control spool and the control opening change proportionally to the control value. The control electronics are integrated into the valve. By adjusting the valve and the electronics, the deviations caused by mass-produced equipment can be kept at a low level.
Do not let the fuel tank pipeline run empty; under the corresponding installation conditions, a preload valve (with a preload pressure of approximately 2 bar) must be installed.
Valve Features
The basic setting of the secondary valve includes our proportional valve module. The zero-potential adjustment of the "main stage zero potential" is preset at the factory and can be adjusted within ±30% of the nominal stroke through the potentiometer in the control electronics. The integrated control electronics can be serviced only after removing the protective plug in front of the cover housing. The replaced pilot control valve or control electronics must be readjusted. All adjustment work can only be performed by professional personnel.
Attention!
Changing the zero potential may cause system damage, so it can only be performed by professional personnel!

Safe - The fail-safe position of the control spool is closed
Energy-saving - No pilot oil is required
High quality - Control spool and sleeve with servo valve performance
Flexible - Suitable for position, rate and pressure control
- High response sensitivity and low hysteresis
IO-Link interface, optional
The 4WRPEH type valve is a direct-acting directional control valve with electrical position feedback and integrated electronics (OBE).
Structure
The 4WRPEH high-frequency response valve mainly includes:
Valve housing with control spool and sleeve with servo performance
Control coil with position sensor (optional electronic component protective film)
Integrated electronics (OBE) with analog or IO-Link interface (optional damping plate)
Function
The integrated electronics (OBE) compares the control value with the actual position value. In case of a control deviation, the stroke coil will be activated. Due to the change in the coil magnetic force, the control spool will adjust against the spring. The stroke/control spool cross-section is controlled in a manner proportional to the control value. When the preset control value is 0, the electronics adjusts the control spool against the spring to the center position. In the deactivated state, the spring is in a relaxed state, at this time the spring length is long, and the valve is in the fail-safe position.
Control coil cut-off
In the following fault conditions, the integrated electronics (OBE) de-energizes the control coil, and the control spool will be set to the fail-safe position:
Below the minimum power supply voltage
Only when the interface is "F1":
The current value is below the minimum current control value of 2 mA (including cable interruption of the control value line (current loop))
Only when the interface is "L1":
Enable is not activated, communication is interrupted (watchdog)
When an internal IO-Link fault occurs
Only when the interface is "C6":
Extra release is not activated
Damping plate "D"
The damping plate reduces the acceleration amplitude on the integrated electronics (frequency >300 Hz).
Note:
For applications with mainly low excitation frequencies (
Electronic component protective film "-967"
To protect against condensation in the housing of the integrated electronics (OBE), an electronic component protective film can be used.
It is recommended for use in external industrial standard conditions (such as outdoors) with high air humidity and significant periodic temperature changes.

Maximum working pressure: 350 bar
Maximum flow rate: 3000 l/min
Rated flow rate: 25 … 1000 l/min
Reliable - Proven and robust design
Safety
- Automatic pressure compensation in the main control chamber, achieved by means of a pilot control valve
- The main control spool is in the spring-centered position and/or offset position
- Optional spool position monitoring
Flexible - Suitable for position, rate and pressure control
- High response sensitivity and low hysteresis
The 4WRTE type valve is a pilot-operated directional control valve with electrical position feedback, integrated electronics (OBE) and optional spool position monitoring.
Configuration
The basic valve consists of 3 main components:
A housing with a main control spool and optional spool position monitoring
Integrated electronics with a main inductive position sensor (optional electronic component protective film)
A pilot control valve with a control spool/socket device, an inductive position sensor and pressure feedback at the center position of the main control spool
Function
After the proportional solenoid is de-energized, the main control spool will be held in the center position by the centering spring and pressure feedback
The main control spool is controlled by the pilot control valve → The main control spool is in the adjusted position
The control spool of the pilot control valve is controlled by changing the magnetic force of the coil of the proportional solenoid
Connection between the control value and the theoretical value of the integrated electronics
The pilot oil can be supplied to the pilot control valve internally through port P or externally through port X. The return oil of the pilot oil is drained to the tank internally through port T or externally through port Y
When the control value is 0 V, the electronics control the main control spool in the center position.
Spool position monitoring
The spool position of the main control spool is detected by a position sensing switch and then displayed through two switching outputs with preset logic. If the fixed set switching point is exceeded, the deviation from the zero position will be monitored in the control spool cover (see "Accessories").
These switching signals can be used in the advanced control for monitoring functions. The electrical connection is made separately through a 4-pole connector M12x1 with two signal output pins and two power supply pins.
Application fields
The valve can be used in safety-related dual-channel applications (Category 3, PL d and Category 4, PL e according to EN *********standard), such as a closing element for one channel. The valve meets the safety start-up and shutdown requirements of stop category 0 in EN 60204 standard.
If safety requirements are needed, the power supply voltage of the valve must be safely cut off based on
the required safety level (Category PL).
According to the application and working equipment requirements - in line with the specific standards of EN 13849-1, the user must provide
the appropriate monitoring/credibility check that meets the required diagnostic range DCavg and uses advanced control.
Electronic component protective film “-967”
To protect the condensation format in the integrated electronic component (OBE) housing, an electronic component
protective film can be used.
It is recommended for external industrial standard conditions with high air humidity and obvious periodic temperature changes (e.g., outdoors).
Power supply voltage failure
Once a power supply voltage failure or cable interruption occurs, the integrated electronic component will stop supplying power to the coil
Automatic pressure control through the pilot control valve at the same level of the control chamber
In the case of a pressure supply failure, the main control spool is centered by the centering spring
Center position of the main control spool
Note:
A power supply voltage failure will cause the control shaft to suddenly stop. The acceleration force generated in this connection may cause mechanical damage.
For control spools with symbols E, E1-, W6-, and W8-, the centering spring places the main control spool in the center position. The V- and V1 control spools have been switched to the priority directions P to B and A to T, and the tolerance range of the control spool stroke is from 1% to a maximum of 11%.
The PG assembly must not be opened. The mechanical adjustment of the adjusting nut located below is disabled, as this operation will damage the valve.
The zero potential setting has been completed at the factory. Note: Changing the zero potential may cause system damage, so it can only be performed by professional personnel.
If the pilot control valve or electronic component is replaced, the zero potential must be readjusted by a trained expert.

Pilot-operated proportional directional valve models 4WRZ(E)… and 5WRZ(E).52…
Valves of model 4WRZ(E)... are pilot-operated four-way directional valves actuated by proportional electromagnets. Their function is to control the flow direction and flow rate.
Valves of model 5WRZ(E)… are equipped with an additional oil port “R” (limited to NG52).
Configuration:
The basic composition of the valve includes:
Pilot control valve with proportional electromagnets
Main valve with main control spool and centering spring
Function:
After the coil is de-energized, the main control spool will be held in the center position by the centering spring.
The main control spool is controlled by the pilot control valve; the main control spool moves proportionally, for example, by activating coil “b”.
→ The control spool moves to the right. The pilot oil flows into the pressure chamber through the pilot control valve and rotates the main control spool proportionally according to the electrical input signal.
→ Connections from P to A and from B to T are made through the throttling cross-section with progressive fluid characteristics
The pilot oil can be supplied to the pilot control valve internally through port P or externally through port X.
Coil is closed
→ The control spool and the main control spool move back to the center position
Depending on the spool position, the hydraulic oil can flow from P to A, from B to T, or from P to B, from A to T (R).
Manual emergency operation is optional, which can be used to move the control valve spool when the coil is de - energized.
Note:
Accidental activation of the manual emergency operation may cause uncontrolled machine movement!
Note:
Due to the design principle, there is inherent internal leakage in the valve, and the leakage volume may increase with the service life.
