The H5-4WE10M5X/EG24N9K4/B30M valve belongs to the 5-4WE Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic automation where electrical actuation shifts oil flow between machine actuators. Size 10 defines its mounting envelope and flow cross-section, while the ISO 4401-05-04-0-05 porting pattern lets the body bolt directly to standard sub-plates. The valve supports 420 bar at ports P, a, and b so it can control high-pressure supply lines, and it allows 210 bar on port T to protect the return path from overpressure. A maximum flow of 150 l/min sets the highest volume it can route without excessive pressure loss. The 20/18/15 cleanliness class under ISO 4406 specifies the oil purity level needed to prevent spool scoring and ensure reliable movement. An NBR sealing system prevents external leakage and keeps compatibility with typical mineral hydraulic fluids.
The coil section operates from a nominal 24 V DC supply so it can be driven by common machine control power, and a ±10 % voltage tolerance maintains function during modest supply fluctuation. Electrical consumption is fixed at 40 W, which defines the load to be considered in power-supply sizing. A 100 % duty cycle (S1) permits continuous energization without requiring cool-down periods, and the surface of the coil may reach up to 140 °C before thermal limits are exceeded. Connection is made through a DIN EN 175301-803 plug to streamline wiring and maintenance. An IP65 protection class guards internal parts against dust ingress and low-pressure water jets in industrial environments. The assembly can switch up to 15 000 cycles per hour, enabling rapid directional changes in high-speed hydraulic systems.
