4WRL25V300P-3X/G24Z4/M

The 4WRL25V300P-3X/G24Z4/M valve is part of the 4WRL Solenoid Valves series from Bosch Rexroth and is intended for directional control in hydraulic automation systems. Its nominal size of 25 provides a port cross-section suited for machinery that needs substantial flow capacity. A mounting interface conforming to ISO 4401-08-07-0-94 allows direct installation on standard manifolds, simplifying block design. The valve carries the V symbol for a 4/3-way configuration, so it can route pressure, tank, and actuator lines in neutral and two active positions. A non-linear P flow characteristic permits fine metering near the center position while still enabling full stroke delivery. At a pressure drop of 10 bar the nominal flow reaches 300 l/min, delivering reliable actuator speed under typical working conditions, and the design tolerates up to 900 l/min when systems demand peak throughput. Main-stage ports p, a, and b withstand 350 bar to accommodate high-pressure circuits, while ports t, x, and y remain limited to 250 bar to protect return and pilot channels.

External pilot oil supply and return keep control oil separate from the main stream, and the circuit only needs a minimum pilot pressure of 10 bar to shift the spool reliably. The solenoid accepts a 24 V DC supply so it integrates with common machine wiring, and coil current is limited to 2.7 A to match typical driver cards. Electrical power consumption stays at 40 VA, which helps panel designers size power supplies without overspecification. Connection to the coil is made through a DIN 43560-AM2 line socket, providing quick plug-in serviceability. The unit seals with NBR elastomers to ensure compatibility with conventional mineral hydraulic fluids. Total mass is 18 kg, giving the assembly sufficient rigidity against vibration while remaining manageable for one-person handling during maintenance. Together these features complete the electrical, hydraulic, and mechanical profile required for stable control of cylinders and motors in industrial equipment.
