The 3DREE16P-7X/250YG24K31A1V valve belongs to the 3DR Pressure Reducing Valves series from Bosch Rexroth and is used to maintain a controlled downstream pressure in hydraulic automation circuits. Electrical actuation with integrated electronics allows the valve to be commanded directly by a control system without an external amplifier. A 24 VDC supply powers the electronics, ensuring compatibility with standard industrial power rails. The unit accepts a 0 – 10 V command signal so proportional pressure settings can be established via an analog output. A 7-pole (6+PE) connector according to EN 175201-804 provides a removable interface for power and control wiring. Two switching positions let the valve toggle between open and regulated states with defined response. The P → A spool path defines the pressure-reducing flow direction inside the manifold. Porting follows connection diagram ISO 4401-07-07-0-05, which simplifies stacking with standard subplates.
Nominal size 16 determines the internal flow passages and aligns the valve with common manifold channels. A maximum operating pressure of 315 bar allows use in high-pressure circuits. The design supports up to 300 l/min, letting it handle large actuator demands. Four ports provide separate connections for pressure, tank, and control lines, which facilitates closed-loop pressure regulation. Subplate mounting enables quick installation and replacement without disturbing pipework. FKM seals resist hydraulic oil and higher temperatures, extending service life. The valve weighs 10.241 kg, so mounting surfaces must support that mass during operation.
