Three-way pressure relief valve type 3 DREP 6.. Direct motion operation by proportional electromagnet. It converts electrical input signals into proportional pressure output signals. Proportional electromagnets are controllable wet pin DC coils with centering threads and detachable coils. These coils can be selectively controlled by external control electronics (type 3DREP) or integrated control electronics (type 3DREPE).
Settings:
The basic components of the valve include:
Shell with connecting surface
Control spool with pressure measuring spool
coil with centering thread
Optional integrated control electronics
Function:
Set the pressure in A or B by proportional electromagnet. The amount of pressure depends on the current. When the coil is de-energized, the control spool is held in the center position by a compression spring. Ports A and B are connected to T so that hydraulic oil can flow unimpeded into the tank. By energizing the proportional solenoid (e.g. coil a), the pressure measuring spool and the control spool will move to the right. This will open the connections from P to B and from A to T by throttling cross-sections with progressive fluid characteristics. The pressure built up in passage B acts on the control spool through the surface of the pressure measuring spool, resisting the magnetic force of the coil. The pressure measuring spool is supported by coil b. If the pressure exceeds the value set on coil a, push the control spool back against the coil magnetic force and establish the connection between B and T until the set pressure is reached again.
Pressure is proportional to coil current. When the coil is closed, the control spool returns to the center position under the action of the compression spring. Optional manual emergency operating element moves the control spool without energizing the coil.
Note:
Accidental activation of manual emergency operating elements may result in uncontrolled machine movements!
Valves with two spool positions (Model 3DREP.. A.. or 3DREP.. B..）：
Basically, the function of this valve corresponds to that of a valve with three spool positions. However, dual spool position valves are only equipped with coil a or coil b. It is fitted with a protective plug instead of a second proportional electromagnet.
Note:
Do not allow tank lines to run empty. A preload valve (preload pressure approx. 2 bar) must be installed under the appropriate installation conditions.
Control value:
Reference potential at E and positive control value at D (or 12... 20 mA) causes pressure at A.
Reference potential at E and negative control value at D (or 12... 4 mA) causes pressure at B.
Through the valve with coil on side b(type A), reference potential at E and positive control value at D (4... 20 mA) will cause pressure at A.
Through a valve with coil on side a(type B), reference potential at E and positive control value at D (4... 20 mA) will cause pressure at B.

summarize
Proportional relief valve DBE6X is a pilot operated relief valve.
The inner pilot stage of the cone-seat type and the main stage of the spool type are both in the valve body.
Control by proportional electromagnet. The electromagnet is damped by a throttle valve in the armature to ensure dynamic stability. The inner cavity of the electromagnet is connected with the interface I and filled with hydraulic oil.
Venting can be done via screw plugs.
These valves allow the system pressure to be limited to be adjusted in a stepless manner according to coil current variations.
fundamental
The system pressure is regulated by determining a setpoint value via the electronic control unit. The electronic control unit uses the regulated PWM current according to the set value
(PWM pulse width modulation) controls the coil coils. Oscillating signals are used to modulate the regulated current to ensure minimal hysteresis.
Proportional electromagnets convert the current into mechanical force and act on the main spring in the pilot stage via armature tappets. Control oil at a flow rate of 0,6 l/min is supplied to the pilot stage via the oil supply bore.
Pressure levels are determined by taper/socket configurations.
Provides * a high degree of overvoltage protection: pmax.
If a fault occurs in the electronic control unit and the coil current (1max) is exceeded as a result of the runaway, overvoltage protection is ensured by * a large spring force.

general information
Proportional relief valves DBETX are remote control valves (pilot control valves) of spool-seat design. This valve is used to limit system pressure.
Operates via proportional coils.
The coil interior is connected to port T and filled with hydraulic oil.
With this valve, the system pressure to be limited can be adjusted via the control electronics according to the coil current at a flow rate of 1 l/min that is as constant as possible.
The valve is basically composed of housing, proportional coil, valve seat and valve core.
fundamental
Preset control values on the control electronics for setting the system pressure. The electronics control the solenoid coil according to the control value by means of a regulated PWM current (pulse width modulation). The proportional coil converts the current into mechanical force, which acts on the main spring through the armature plunger. A compression spring between spool and seat ensures stability and low residual pressure. The spring force on the spool and the pressure in the seat counteract at a constant oil flow (0.7 - 1 l/min). The high pressure rating is determined by the spool/seat bore configuration.
high pressure limit
Large spring forces are critical for pressure limitation in the event of failure or damage to the control electronics, resulting in uncontrolled excess coil current (Imax).

summarize
DREBE6X proportional pressure reducing valve is pilot type, the main stage is three-way structure. Control oil with regulated flow is supplied to the pilot valve (DBV-pilot stage) via Р.
Control via position-adjustable proportional electromagnet with built-in electronic control unit. With these valves, the pressure in A(load) can be continuously adjusted and reduced according to the set value.
fundamental
The system pressure in A is regulated by determining a setpoint value via the electronic control unit. The electronic control unit controls the position of the electromagnet against the spring force according to the set value. Proportional electromagnets are accurately positioned according to spring characteristic curves. Hydraulic oil with a flow rate of less than 0.6 l/min is supplied to the pilot stage via the flow regulating valve from Р.
Compare and adjust the pilot pressure to the load pressure (applied spring force) in A. The spring makes PAmin=P in T.
Provides * a high degree of overvoltage protection
If a fault occurs in the electronic control unit and the coil current (1ax) is exceeded as a result of the runaway, overvoltage protection is achieved primarily by the large spring force.

function
DBEM valve is a pilot operated relief valve. These valves are used to limit the working pressure of hydraulic systems. Depending on the electrical control value, these valves can be used for stepless setting of the system pressure to be limited. The basic components of these valves include a housing with a main spool, a superposition valve with a large pressure limit, and a proportional pilot control valve.
Model DBEM...
Pressure applied in passage P acts on the main spool. At the same time, pressure at port P is applied to the spring-loaded side of the main spool through the control circuit with nozzle. Pressure is also applied to the frame of the proportional pilot control valve through the connecting bore. The hydraulic pressure at the pilot seat overcomes the proportional solenoid control value-dependent force. If the hydraulic pressure exceeds the coil magnetic force, the pilot seat opens. Pilot oil can now flow through the control circuit to port Y and to the tank; therefore, a pressure drop occurs at the main spool on the control circuit. Release the connection from port P to T. The main spool controls the set operating pressure at port P. Since hydraulic protection prevents impermissible high pressure values, spring-loaded relief valves are integrated. This high pressure limit is a preset value based on the relevant pressure level. Within the valve operating range, the spring holds the valve holder to the valve seat and the valve core closes thereby. If the pressure at the main spool spring chamber exceeds the valve's maximum allowable set point pressure, the carrier will press against the compression spring and the connection to the spring chamber will open. Pilot oil flows into the tank through port Y. Due to the presence of the control circuit, a pressure drop occurs at the main spool. Release the connection from port P to T. The main spool controls the large operating pressure set at port P. If necessary, the preset pressure can also be reduced by means of an adjusting element. Port Y must be connected from the outer tube to the tank. The tank must be connected after pressure relief. The valve can be unloaded or high pressure limited through port X.

Spring-loaded relief valves are integrated since hydraulic protection prevents abnormally high pressure values. This high pressure limit is a preset value based on the relevant pressure level. Within the valve operating range, the spring holds the valve holder to the valve seat and the valve core closes thereby.
If the pressure at the main spool spring chamber exceeds the valve's maximum allowable set point pressure, the carrier will press against the compression spring and the connection to the spring chamber will open. Pilot oil flows into the tank through port Y. Due to the presence of the control circuit, a pressure drop occurs at the main spool. Release the connection from port P to T. The main spool controls the large operating pressure set at port P. If necessary, the preset pressure can also be reduced by means of an adjusting element. Port Y must be connected from the outer tube to the tank. The tank must be connected after pressure relief. The valve can be unloaded or high pressure limited through port X.

The DBET Proportional Relief Valve is a remotely controlled valve with a seated design that can be used to limit system pressure. Operates with proportional electromagnet with centering thread and detachable coil. The inside of the coil is connected to port T or Y and filled with hydraulic oil. Depending on the electrical control value, these valves can be used for stepless setting of the system pressure to be limited. The valve is mainly composed of shell, proportional electromagnet, valve seat and valve frame.
fundamental
To set the system pressure, control the value at the control electronics. The electronics drive the solenoid with current according to the control value. The proportional electromagnet converts the current into mechanical force, which acts on the valve frame through the armature plunger. Push the valve holder into the seat and block the connection between port P and T or Y. If the hydraulic pressure on the carrier is equal to the coil magnetic force, the valve controls the set pressure by lifting the carrier off its seat, allowing hydraulic oil to flow from port P to T or Y. If the control value is zero, the control electronics apply only a small control current to the proportional electromagnet and a small constant pressure is also set.

SetPoint Manufacturing tolerances for pressure characteristic curves are small
Proportional Relief Valve Type DBETE is a remotely controlled valve with seat design and integrated electronics for limiting system pressure. Operates with proportional electromagnet with centering thread and detachable coil. The inside of the coil is connected to port T or Y and filled with hydraulic oil. Depending on the electrical control value, these valves can be used for stepless setting of the system pressure to be limited. The valve is mainly composed of housing, proportional electromagnet, valve seat, valve frame and integrated electronic components. Apply the supply voltage and control value voltage to the connector. The pressure characteristic curve of the control value is adjusted to very low manufacturing tolerances at the factory.
