The DRE4K-4X/30G24-10K4M is produced by Bosch Rexroth within the DRE Proportional Reducing Valves series and is applied to modulate pressure in hydraulic automation circuits. With a nominal size of 4, the unit fits compact manifold cavities and remains normally closed when de-energized. Direct-acting operation simplifies response, while electro-proportional actuation lets the controller vary pressure continuously with a 24 V DC supply. The coil shows a resistance of 12 Ω at that voltage, and drivers are tuned to a 200 Hz PWM frequency to hold stable pressure steps. Electrical connection is through a DIN EN 175301-803 K4 plug, and the design includes no manual override, so pressure adjustment relies only on the electrical signal.
A cavity diameter of 16 mm allows drop-in installation in standard valve blocks. The component provides three ports to separate inlet, regulated outlet, and tank lines, and it supports flows up to 6 l/min. Maximum operating pressure on the inlet side is 100 bar, while the set pressure at port A can be adjusted up to 30 bar for downstream protection. NBR seals maintain fluid compatibility, and the assembly weighs 0.4379 kg, helping keep actuator stations light.
