4WRPH6C3B04L-2X/G24Z4/M

The 4WRPH6C3B04L-2X/G24Z4/M valve belongs to the 4WRP Solenoid Valves series produced by Bosch Rexroth. It is used in hydraulic automation to meter flow and direction in servo-controlled circuits. The integrated amplifier operates from a 24 V DC supply, allowing direct connection to common machine control power rails. A coil resistance of 2.5 Ω determines the heat rise and sets the electrical load seen by the drive card. During full stroke, the solenoid draws up to 2.7 A, so wiring and fusing must accommodate that peak. Electrical demand stays within 40 VA, which helps designers size power supplies in multi-axis manifolds. With a nominal flow of 4 l/min at a 35 bar differential, the valve regulates small actuators with fine resolution. Valve size 6 (NG6) keeps the envelope compact for stacked sub-plate mounting. A response time of no more than 10 ms supports closed-loop position tasks that need rapid spool movement. The aluminum body carries an IP65 rating, preventing dust ingress and water jets from affecting operation in industrial plant environments.

Maximum service capability reaches 315 bar on the P, A, and B ports, while the tank port tolerates 250 bar, so the unit can be installed in high-pressure servo loops without external relief devices. The mounting surface follows ISO 4401-03-02-0-94, ensuring interchangeability with existing NG6 manifold blocks. Spool position feedback is provided as a ±10 V signal, which pairs directly with most motion controllers for real-time monitoring. That transducer is energized by a ±15 V supply drawing 35 mA, so control cards need only a small auxiliary regulator. Electrical termination for the solenoid uses a DIN 43650/ISO 4400 connector with an M16×1.5 thread, facilitating quick coil replacement, whereas the position sensor leads exit through a separate 4-pin Pg7 plug to segregate analog feedback from coil currents. Total mass is 2.3 kg, allowing the valve block to be handled easily during maintenance. These characteristics let system designers implement precise, high-speed flow control while maintaining standard mounting, wiring, and pressure interfaces.
