The 4WE6F19B6X/EG24N9K4/ZV directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is used to route pressurized oil in hydraulic automation. It mounts on subplates that follow the ISO 4401-03-02-0-05 pattern and the equivalent NFPA T3.5.1 D03 interface, allowing interchange with common manifolds. A clamping length of 22 mm secures the housing to the block without additional spacers. FKM seal material resists high-temperature fluids and maintains tight leakage control. The valve tolerates operating pressures up to 350 bar at ports a, b, and p, while the tank port handles 210 bar during direct-current operation. When fully opened it carries up to 80 l/min and can run continuously because the solenoid is specified for a 100 percent S1 duty cycle.
Electrical power is supplied at a nominal 24 V DC through a DIN EN 175301-803 three-pin connector labeled K4. Under that voltage the coil draws a rated current of 1.25 A and dissipates 30 W. A concealed manual override identified as N9 lets service personnel shift the spool mechanically during setup or fault conditions. The design limits switch-off overvoltage to 500 V, protecting upstream drivers when the magnetic field collapses. A maximum switching frequency of 4.2 strokes per second supports rapid directional changes in cyclic machinery. With the mating plug fitted, the enclosure attains IP65 protection against dust and low-pressure water jets.
