The 4WRTE10V100L4X/6EG24K31/A1M valve is manufactured by Bosch Rexroth as part of the 4WRTE Directional Control Valves series. It provides electro-hydraulic position control for cylinders and motors in automated machinery. The nominal size NG10 defines the mounting cavity and matches medium flow applications. A rated flow of 100 l/min at a 5 bar control edge pressure drop sets the maximum volume the valve can handle without excessive losses. The unit tolerates up to 350 bar on ports P, A, and B, enabling operation in high-pressure circuits. A ±10 V command and feedback interface permits closed-loop regulation from analog motion controllers. The onboard electronics run from a 24 VDC supply, and they remain functional between 18 VDC and 35 VDC to cope with line fluctuations. During peak demand the valve draws 1.6 A, and its total electrical load is limited to 72 VA.
An external pilot oil supply separates control flow from the main line, while an external pilot oil return allows the spool to exhaust independently and avoids contamination of the tank line. The ISO 4401-05-05-0-05 porting pattern standardizes manifold mounting so the valve drops into common sub-plates. A DIN EN 175201-804 (K31) plug provides the electrical connection and enables quick replacement without rewiring. The enclosure carries an IP65 protection class, sealing the electronics against dust ingress and low-pressure water jets. Return pressure at port T may reach 315 bar, a limit that maintains spool stability when backpressure builds in the tank circuit. Total mass is 8.7 kg, a factor to consider when sizing manifold supports and handling equipment.
