The 4WEH10JA4X/6EG24K4QM0G24 is a directional spool valve in the WEH Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation circuits that require reliable on-off and flow routing functions. It is built to the NG10 nominal size so it fits manifolds and sub-plates designed for that passage area. A maximum flow capacity of 160 l/min allows it to handle medium to high system throughput without excessive pressure loss. The ISO 4401-05-05-0-05 porting pattern aligns the work ports and fixing bolts so the valve can be dropped onto common CETOP 05 layouts. Three spool positions give operators neutral, extend, and retract states for cylinders or motors. A 24 V DC coil energizes the pilot solenoid, matching standard machine control voltages. The DIN EN 175301-803 K4 electrical connector provides a sealed plug-in interface for quick field wiring. External pilot oil supply prevents pressure drop through the control stage, while external pilot oil return stops back-pressure from influencing spool movement.
System limits are defined by 280 bar on the P, A, and B ports, 280 bar on the T port, and 210 bar on the external Y drain so that each flow path is protected against overload. Pilot actuation starts at 12 bar and is rated up to 250 bar, ensuring consistent shifting across a wide control pressure window. NBR seals are fitted to resist mineral hydraulic oils and maintain tight separation between ports. Rest-position monitoring identified by code QM0G24 feeds a signal to the PLC whenever the spool is in neutral, supporting machine safety interlocks. Cleanliness class ISO 4406 20/18/15 sets the required oil filtration level to keep the metering edges free of abrasion. Together, these limits and features establish the valve as a precise, electrically piloted component for directional control in industrial hydraulic systems.
