The Z4WE6E53-20 directional spool valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series to control oil flow in hydraulic automation circuits. The unit employs a wet-pin solenoid for actuation, keeping the core submerged for quiet operation and long service life. It is direct-operated, so no pilot stage is required and response time stays low. The nominal size is 6 (NG6), giving a compact form factor for manifold assemblies, and the sandwich plate mounting style aligns it with modular stack systems. A maximum operating pressure of 315 bar supports high-pressure machinery, while the valve passes up to 50 l/min to accommodate medium flow demands. The coil withstands surface temperatures to 120 °C for reliable continuous use, and a voltage tolerance of ±10 % allows stable performance despite supply deviations.
The port layout follows ISO 4401-03-02-0-05 (NFPA D03), ensuring compatibility with standard subplates, and four ports provide P, T, A, and B connections. Internal metering matches spool symbol E53, defining the flow paths in neutral and energized positions. The solenoid is rated for a 100 % duty cycle (S1), so it may remain energized without cooling intervals. When fitted with a K4 connector the enclosure achieves IP65, blocking dust ingress and low-pressure water jets. Electrical hookup uses an EN 175301-803 three-pole 2+PE plug to simplify field wiring and grounding. Approved operating media include HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR fluids, enabling use with mineral oils, biodegradable options, or fire-resistant formulations.
