The 4WE6EB6X/EW110RNXEZ2/V directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth. It switches flow paths in hydraulic automation systems, enabling actuators to extend, retract, or hold position under controlled pressure. The valve withstands a maximum pressure of 350 bar at ports P, A, and B, so it can be installed in high-pressure supply circuits. A permissible 160 bar at port T maintains safety on return lines that experience back-pressure. Its nominal flow rate is 60 l/min, giving adequate volume for medium-capacity cylinders and motors. The solenoid operates on 110 V AC at either 50 or 60 Hz and draws 0.34 A, eliminating the need for frequency-specific coils. Class H insulation protects the winding under elevated temperatures, while the coil surface can reach 120 °C during prolonged energization. A mechanical override is provided, but its use is limited to tank pressures up to 50 bar to avoid damage.
FKM sealing elements tolerate common hydraulic oils and higher temperatures, reducing leakage over long service intervals. Cleanliness requirements of ISO 4406 20/18/15 must be met to keep spool clearance free from abrasive particles. An IP65 housing prevents dust ingress and resists water jets during wash-down. The body follows mounting pattern ISO 4401-03-02-0-05, making it compatible with standard subplates in modular manifolds. This pattern corresponds to NFPA size D03, so North American base plates can be used without adapters. Proper installation requires tightening the four mounting screws to 7 Nm to ensure seal compression without distorting the casting. Functional safety is supported by a mean time to dangerous failure of 300 years, indicating a very low probability of critical malfunction within normal service life.
