Product Overview
The Rexroth DRP 4 K-4X/30G24-10N9K4M (Material No. R901202971) is a direct-operated, proportional pressure reducing valve from the Bosch Rexroth DRP series, size 4 (NG4 / CETOP 3 interface). It is designed to reduce a primary system pressure to a steplessly adjustable secondary pressure at port A, proportional to the electrical command signal applied to the integrated proportional solenoid. The valve operates on a spool-and-sleeve pressure-reduction principle: the proportional solenoid acts on the control spool against a compression spring, and an internal pressure feedback gallery continuously balances the spool so that outlet pressure remains stable and largely independent of flow demand and inlet pressure fluctuations. With a 4X series design (component series 40 to 49, installation and connection dimensions unchanged), a 30 bar pressure rating stage, and a 24 V DC / 10 N solenoid with N9K4 electrical connection, this valve is engineered for precise, electro-proportional pressure control in industrial hydraulic power and control circuits. As a genuine Rexroth proportional valve, it serves as a direct-fit replacement for OEM installations requiring accurate pressure regulation, smooth ramp response, and high repeatability.
