The 4WRREH6VB15P-1X/G24K0/B5M-847 belongs to the 4WRE Proportional Directional Valves series and is manufactured by Bosch Rexroth for closed-loop hydraulic automation. The valve performs 4/3-way control so it can direct flow to either service line or block ports in the center position. A nominal flow of 15 l/min at a 70 bar pressure drop sets the throughput that system designers can expect when sizing actuators. Non-linear P flow characteristic provides progressive metering that matches load requirements at small spool displacements. Ports p, a, and b withstand working pressures up to 315 bar, while the tank port is limited to 100 bar to protect return circuits. A step response of 5 ms from 0 to 100 % enables rapid position changes, and hysteresis held to 0.2 % minimizes deviation between command and actual flow. The ±10 V input signal accepts common analog controller outputs for straightforward integration.
The solenoid electronics are fed with 24 V DC, and a power consumption of 30 VA defines the supply capacity that must be available in the control cabinet. Continuous operation is permitted because the duty cycle is 100 %. An IP65 housing seals out dust and water jets, allowing installation on machinery exposed to fluid spray. The 11P+PE plug provides a single connector for power and signal conductors, reducing wiring time. The ISO 4401-03-02-0-94 mounting pattern lets the valve bolt directly onto standard sub-plates without additional adapters. Fluid entering the unit must meet ISO 4406 cleanliness level 18/16/13 to prevent spool wear and sticking. Total mass is 2.5 kg, light enough for manifold assemblies that need low inertia during maintenance.
