The 4WRPH6C4B02L-2X/G24Z4/M valve belongs to the 4WRP Solenoid Valves series manufactured by Bosch Rexroth for hydraulic automation where precise flow control is required. Its nominal size 6 fits NG6 cavities, and the ISO 4401-03-02-0-94 mounting interface keeps the unit interchangeable with standard subplates. A C4 spool pattern defines the metering edges so balanced flow reaches both service lines. The valve passes 2 l/min at a 70 bar differential, making it suitable for low-volume circuits that demand accurate regulation. Pressure capability is 315 bar on ports P, A, and B, while the tank line withstands 250 bar, allowing use in high-pressure power units. A 24 V DC supply energizes the solenoid, and the 2P+PE connector with an M16 × 1.5 thread secures power and protective earth for consistent operation.
The coil is rated for a 100 % ED duty cycle, supporting continuous energization and rapid sequencing without thermal derating. Spool position is monitored by an LVDT in DC/DC format, and feedback reaches the controller through a four-pole Pg7 transducer connector. An IP65 enclosure guards against dust and water jets once the plugs are fitted, so the valve can mount near splash zones. NBR seals confine the hydraulic fluid and remain compatible with mineral oil grades HL and HLP specified for the unit. System cleanliness must stay at ISO 4406 (c) 18/16/13 to preserve spool linearity and prevent stick-slip. A weight of 2.3 kg eases single-person installation and limits bending load on compact manifolds.
