The Z4WE6E63-3X/EG24N9K4/V valve is manufactured by Bosch Rexroth for the Z4WE Solenoid Actuation Spool Valves series and is used to shift hydraulic flow paths in automated machinery. Its solenoid is energized by a rated voltage of 24 V DC while drawing a rated current of 1.25 A to move the spool between positions. Electrical connection is provided through a DIN EN 175301-803 (K4) plug that matches standard industrial harnesses. The enclosure carries an IP65 protection class, enabling installation in areas exposed to dust and water jets. Four mounting holes of Ø5.3 mm hold the body firmly on a subplate, and the porting pattern matches ISO 4401-03-02-0-05 for interchangeability with CETOP 3 manifolds. An FKM seal set supports a broad range of hydraulic media, and a manual override tolerates tank pressure up to 50 bar so the spool can be shifted without electrical power.
The hydraulic section accepts operating pressures up to 315 bar at ports P, A, and B, permitting use in high-pressure circuits, while port T is limited to 210 bar to protect the return line. The design passes up to 50 l/min, covering medium flow requirements in machine tools and assembly equipment. Fluids with viscosities as high as 500 mm²/s are accommodated without impairing response time. Service is allowed with fluid temperatures from –15 °C to +80 °C, ensuring reliable switching during cold starts and continuous duty. Ambient temperatures may reach +50 °C when FKM seals are fitted, maintaining seal elasticity and preventing leakage. System oil cleanliness must be held to ISO 4406 (c) 20/18/15 to preserve the precision fit between spool and bore.
