Product description
Proportional pressure reducing valves of type DREBE10Z are pilot-operated pressure reducing valves and are used for system pressure limitation. They are actuated by a position-controlled proportional solenoid with integrated electronics. A logic element (spool valve) is located in the valve housing in the “normally open” version, pilot-operated in poppet seat version.
