The six-way pilot-operated proportional pressure reducing valve DREBE 6X-1X series adopts a pilot design, which can reduce the main valve core driving force and improve the response speed (frequency response can reach more than 10Hz). The six-way structure reduces the complexity of the pipeline and is suitable for compact spaces. Valve DREBE 6X-1X supports standard industrial communication protocols (such as PROFINET, EtherCAT), which is easy to integrate into intelligent hydraulic systems.

Application:
Proportional pressure reducing valve DREBE 6X-1X series is a high-performance component in industrial hydraulic systems, suitable for complex working conditions that require precise pressure control and dynamic response such as construction machinery, metallurgical equipment, injection molding machines and die-casting machines.
General
Type DREBE6X proportional pressure reducing valves are pilot operated with a 3-way main stage.
The pilot valve (pressure relief valve pilot stage) is supplied internally with a controlled flow of pilot oil via P.
The valves are actuated by means of a position-controlled proportional solenoid with on-board electronics.
With these valves, the pressure in A (consumer) can be infinitely adjusted and reduced in relation to the setpoint.
Basic principle
To adjust the system pressure in A, a setpoint is set in the trigger electronics. Based on this setpoint, the electronics control the position of the solenoid against the spring force. The proportional solenoid is positioned precisely on the spring characteristic curve. The pilot stage is supplied with oil from P at a flow rate of < 0.6 l/min via a flow control valve. The pilot pressure is compared with the consumer pressure (plus spring) in A and regulated.
The spring results in PAmin =p in T.
Pressure limitation for maximum safety
If a fault occurs in the electronics, so that the solenoid current (Imax) would exceed its specified level in an uncontrolled manner, the pressure cannot rise above the level determined by
the maximum spring force.
