Anti-corrosion design
The ZDR type valve is a direct-acting pressure reducing valve with a stacked valve plate design, which can limit the pressure of the secondary oil circuit. It is used to reduce the system pressure.
The pressure reducing valve is mainly composed of a housing, a control spool, a compression spring, an adjustment type and an optional check valve.
The secondary pressure is set through the adjustment type.
Model “A”
The valve is in the open state in the initial position. The hydraulic oil can flow from channel A to channel A without restriction. At the same time, the pressure in channel A acts on the surface of the plunger opposite to the compression spring through the control oil circuit. If the pressure in channel A exceeds the value set at the compression spring, the control spool will be pushed away from the compression spring and move to the control position, so that the set pressure in channel A remains constant.
The control signal and pilot oil are provided from the inside of channel A2 through the control oil circuit.
When the pressure in channel A continues to increase due to the external force acting on the actuator, the pressure will force the control spool to move further away from the compression spring.
In this way, channel A will be connected to the oil tank via the control edge on the control spool and the housing. A large amount of hydraulic oil will flow back to the oil tank, so the pressure will no longer increase.
The leakage oil in the spring chamber is always discharged externally through the hole into channel T (Y).
The pressure gauge connection is used to control the secondary pressure of the valve.
The check valve can be used to achieve free backflow from channel A to A, but only for model “A”.
Models “P” and “B”
For model “P”, pressure reduction can be achieved in channel P. The control signal and pilot oil are provided from the inside of channel P.
For model "B", the pressure in channel P decreases, but the pilot oil can be obtained from channel B.
Precautions:
If the directional valve is in the spool position from P to A, the pressure in channel B shall not exceed the set secondary pressure. Otherwise, pressure reduction will occur in channel A.

The direct-acting valve is used to limit the system pressure.
Operated by a proportional electromagnet.
Proportional electromagnet with centering thread and detachable coil.
For subplate mounting: Hole pattern according to ISO 4401.
Modular amplifier in European board format and as a plug-in amplifier.
Individually adjustable up and down ramps, and the control value-pressure characteristic curve can be finely adjusted.
The DBET type proportional relief valve is a remote control valve with a seat design, which can be used to limit the system pressure. It is operated by a proportional electromagnet with a centering thread and a detachable coil. The inside of the coil is connected to port T or Y and filled with hydraulic oil. According to different electrical control values, these valves can be used to steplessly set the system pressure to be limited. The valve is mainly composed of a housing, a proportional electromagnet, a valve seat and a valve frame.
Basic principle
To set the system pressure, the control value needs to be set at the control electronic component. The electronic component drives the electromagnetic coil with current according to the control value. The proportional electromagnet converts the current into mechanical force, and the mechanical force acts on the valve spool through the armature plunger. The valve spool is pushed into the valve seat and blocks the connection between oil ports P and T or Y. If the hydraulic force on the valve spool is equal to the magnetic force of the coil, the valve controls the set pressure by lifting the valve spool away from the valve seat, allowing the hydraulic oil to flow from oil port P to T or Y. If the control value is zero, the control electronic component only applies a small control current to the proportional electromagnet, and a small set pressure is also set.

The DRE(E) type valve is an electronically controlled pilot-operated three-way pressure reducing valve, which can provide pressure limitation for the electrical appliance. This valve is used to reduce the system pressure.
This valve basically consists of a pilot control valve, a proportional magnet, and a main valve with a main control spool.
Model DRE
Adjust the pressure to be reduced in channel A according to the rated value through the proportional magnet.
When using the relieved port P, the spring keeps the main control spool in the initial position.
Thereby opening the connection from A to T and blocking the connection from P to A.
Pressure connection from port P to the annular channel.
The pilot oil flows from the orifice to port T, through the flow regulator and the nozzle to the pilot control valve, and through the throttle gap to the longitudinal groove and the orifice.
Pressure reduction
The formation of the pilot pressure in the control chamber as a function of the setpoint.
Move the main control spool to the right, and the hydraulic oil flows from P to A.
The electrical appliance pressure is formed in port A of the spring chamber through the channel and the nozzle.
Increase the pressure in port A to the set pressure of the pilot control valve, which will cause the main control spool to move to the left. The pressure in port A is approximately the same as the set pressure of the pilot control valve.
Pressure limitation
If the pressure in port A exceeds the set pressure of the pilot control valve, the main control spool continues to move to the left.
Thereby disconnecting the connection from A to T and limiting the pressure generated in port A to the set setpoint.
Model DREE – With integrated electronics (OBE)
These valves are functionally and structurally in line with the DRE type. A housing with control electronics is also installed on the proportional magnet.
Connect the power supply voltage and the setpoint voltage or setpoint current through the device plug.
Fine-tune the setpoint pressure characteristic curve with a small sample deviation at the factory.

Valves of type DRE(M) belong to pilot-operated pressure reducing valves. These valves can be used to reduce the working pressure.
The basic composition of these valves is a pilot control valve with a proportional solenoid, a main valve with a main spool, and an optional check valve.
Model DRE...
The pressure in channel A can be set according to the control value by the proportional solenoid.
In the rest position – i.e., when there is no pressure in channel B – the spring holds the main spool in its initial position. The connection from channel B to channel A is closed. Thus, start-up jumps can be avoided.
The pressure applied in channel A acts on the surface of the main spool through the hole. The pilot oil flows from channel B through the hole to the constant current control. The constant current control keeps the pilot flow constant, regardless of the pressure drop between channels A and B. The pilot flow flows from
the constant current control into the spring chamber, passes through the holes and, flows into channel Y through the valve seat and returns therefrom. The required pressure in channel A is preset through the relevant amplifier. The proportional solenoid moves the valve frame towards the valve seat and limits the pressure in the spring chamber to the set value. If the pressure at channel A is lower than the preset control value, the higher pressure in the spring chamber will move the main spool to the right. The connection from B to A is opened. If the set pressure at A is reached, the forces at the main spool are balanced - the main spool is in the control position.
Pressure at the spool end face of channel A = Pressure at the spool end face of the spring chamber – Spring force
If in a vertical hydraulic oil column (e.g., the hydraulic cylinder piston in the cut-off position), to reduce the pressure at A (e.g.), a lower control value can be preset through the control electronics, so that a lower pressure value can be pre - selected, and this pressure value will immediately appear in the spring chamber. The higher pressure value at A acting on the surface of the main spool pushes the main spool towards the protection plug to the cut-off position. The connection from A to B is blocked, and the connection from A to Y is opened. The force at the spring currently acts in the opposite direction to the hydraulic force on the surface of the main spool. At this main spool position, the hydraulic oil can flow from channel A through the control edge to Y and enter the return flow.
When the pressure at A drops to the sum of the pressure in the spring chamber and the ∆p of the spring, the main spool will close the large control hole in the socket at the control edge from A to Y.
The remaining pressure difference relative to the new control value at A is about 10 bar. The current pressure can only be unloaded through the control hole. In this way, a good transient response can be achieved without pressure undershoot. To achieve free return flow from channel A to channel B, a check valve can be optionally installed. Part of the filling flow at channel A can also flow into the return flow through the opened control edge from A to Y of the main spool.
Model DREM...
To provide hydraulic protection and prevent an unallowable high electrical control current from appearing on the proportional solenoid, which causes excessive pressure at port A, a spring - loaded relief valve can be optionally installed to limit the maximum pressure. This maximum pressure limit is a preset value based on the relevant pressure level.

The pilot-operated proportional relief valves of type (Z)DBE are activated by a proportional solenoid. These valves can be used to limit the system pressure. Depending on the electrical control value, these valves can be used to steplessly set the system pressure to be limited. The basic structure of these valves consists of a pilot control stage and a main stage. The pilot control assembly consists of a proportional solenoid, a valve frame and a valve seat. The main stage consists of a housing and a main spool assembly. The proportional solenoid converts the current proportionally into mechanical force. An increase in current leads to a corresponding increase in the magnetic force of the coil. The system pressure can be set according to the control value by the proportional solenoid. The pressure applied by the system at channel P acts on the right side of the main spool assembly. At the same time, the system pressure acts on the spring-loaded side of the spool through the control oil circuit equipped with a nozzle. Through the valve seat of the pilot line, the pressure at the valve frame of the spring chamber can overcome the force of the proportional solenoid. When the pressure reaches the preset value, the valve frame will be lifted from the valve seat. At this time, the pilot oil (depending on the model) can drain oil outward through port A (Y) or drain oil to the internal tank, which also limits the pressure on the spring-loaded side of the main spool. If the system pressure continues to rise slowly, the high pressure on the right side of the spool will push the spool to the left to the control position from P to T. At the minimum control current (corresponding to the zero control value), the minimum set pressure will be set.
Attention!
Prevent the fuel tank pipeline from running under no-load. Under the corresponding installation conditions, a preload valve (with a preload pressure of approximately 1 bar) must be installed.

The directional valves of the WE model are solenoid-operated directional spool valves, and this valve can be used as an electromagnetic assembly. They are used to control the start, stop, and direction of the flow.
The basic composition of this directional valve is a housing, one or two electromagnets, a control spool, and a return spring.
In the de-energized state, the control spool is held in the middle position or the initial position by the return spring (except for version "O").
When the electromagnet in the hydraulic oil is energized, the control spool moves from its rest position to the desired terminal 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 an "OF" device and valves without spring type "O").
For auxiliary operation, the valve can be manually switched without energizing the magnet.
The hydraulic system must be properly vented to ensure normal operation.
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 and without a device. Valves without spring return at the control spool have no definite initial position in the de-energized state.
Without spring return, with device "OF" (only applicable to symbols A, C, and D)
This model is a directional valve with two switching positions and two electromagnets and with 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 electromagnet, 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 is opened or closed. Compared with the standard valve, the commutation stroke (measured as the acceleration value a) can be reduced by about 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 a separate return line or install a check valve in the drain line.
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.

Implicit manual emergency operation
The directional valves of the WE model are directional spool valves operated by electromagnetic coils. These valves control the start, stop and direction of the fluid.
These directional valves are mainly composed of a housing, one or two coils, a control spool and one or two return springs. In the case of power failure, the control spool is fixed in the center position or the initial position by the return spring. The control spool is actuated by a coil with wet feet.
To ensure normal operation, please make sure to fill the pressure chamber of the coil with hydraulic oil!
The force of the coil acts on the control spool through the push rod and pushes the latter from its rest position to the required terminal position. In this way, the required flow direction can be released according to the symbol. After the coil is demagnetized, the return spring pushes the control spool back to its rest position.
The manual emergency operation can control the spool when the coil is not energized.
