Bosch Rexroth offers a complete valve family for decentralized control concepts for realizing closed-loop controls of pressure and flow.
These valve units are characterized by a digital controller integrated in the valve with open and closed-loop control algorithms for pressure and flow. The valves are optionally available in two variants, as proportional directional valve 4 WREQ in sizes 6 and 10, with one or two solenoids and up to four integrated pressure sensors. This also allows the evaluation of external pressure sensors.
