The 4WRPEH6C3B15P-3X/M/24A1 belongs to the 4WRP Solenoid Valves series from Bosch Rexroth and is used to regulate pressure and flow in hydraulic automation systems. Its onboard electronics run on a 24 VDC supply that supports precise spool positioning. A ±10 V command value input lets standard analog controllers set valve position, while a 100 kΩ input impedance keeps control circuit load low. Electrical demand peaks at 40 VA, so power supplies can be sized accordingly. Supply ripple must stay below 2.5 Vpp to maintain stable magnetic force, and continuous 100 % duty cycle permits the solenoid to remain energized without overheating. A 2.5 A time-lag fuse protects against overcurrent, and all connections are made through a 6+PE plug that includes a protective earth pin. The housing carries an IP65 rating, blocking dust and water jets encountered in industrial environments.
An ISO 4401-03-02-0-05 mounting pattern allows the valve to bolt directly onto NG6 manifolds and standardizes gasket dimensions. The unit delivers a rated flow of 15 l/min at a 35 bar differential across the control edge, matching medium-capacity actuators. Ports A, B, and P tolerate working pressures up to 350 bar, while port T is limited to 250 bar to safeguard the return line. Hydraulic fluid must meet cleanliness class 18/16/13 per ISO 4406 to limit wear on internal surfaces. All dynamic seals are made of NBR, ensuring compatibility with common mineral oils. A weight of 2.9 kg simplifies manual installation on compact manifold blocks.
