Pilot-operated proportional pressure reducing valves, types DRE(M) and DRE(M)E, in nominal sizes 10 and 25, series 5X, operate up to 315 bar and 300 L/min. They offer precise control with proportional solenoid actuation and plate mounting. They stand out for their initial main piston locking, good oscillation behavior, and options for check valves and pressure safety valves. Compatible with analog and digital amplifiers, the DREE valves have integrated control electronics and independent ramp adjustments.
