Product description
Proportional pressure reducing valves of type DREBE6X are pilot-operated; the main stage is a 3-way version. The pilot control valve (DBV pilot valve) has a flow-controlled internal pilot oil supply via P. It is actuated by a position-controlled proportional solenoid with integrated electronics. Dependent on the command value, the pressure in A (actuator) can be steplessly set and reduced using these valves.
