The 4WRP6C3B04L-1X/G24Z4/M valve is part of the 4WRP Solenoid Valves series manufactured by Bosch Rexroth for precise hydraulic automation. It operates from a 24 V DC supply, and a coil resistance of 3 Ω at 20 °C lets control electronics calculate drive current accurately. The solenoid draws up to 2.7 A with a peak electrical demand of 40 VA, so cabinet power budgets can be set accordingly. A 30 ms response time for a full-scale step change supports fast loop correction, while maximum hysteresis of 0.3 % keeps spool position repeatable. Closed-loop control is achieved through an AC/AC LVDT that tracks spool displacement. The enclosure carries an IP65 rating, protecting internal parts from dust and low-pressure water jets, and that allows installation on machinery exposed to spray or condensation.
The valve mounts on subplates that follow the ISO 4401-03-02-0-94 interface so it can replace or upgrade standard size-03 directional units. Ports P, A, and B withstand working pressures to 315 bar, and the return line endures up to 250 bar, letting the device serve in high-pressure circuits. Internal leakage is limited to 80 cm³ per minute per metering edge at a 100 bar differential, which helps maintain actuator position without excessive pump flow. Hydraulic fluid must meet cleanliness class 18/16/13 per ISO 4406 to protect the LVDT and spool lands, and NBR seals are fitted to resist common mineral oils. Electrical hookup is handled through a DIN 43650 / ISO 4400 connector with two power pins and protective earth, simplifying field replacement. The assembly weighs 2.8 kg, a consideration for manifold support brackets and service handling.
