The 4WRTE10V100P-4X/6EG24TK31/A5M valve is manufactured by Bosch Rexroth as part of the 4WRTE Directional Control Valves series and is used to meter flow in hydraulic automation circuits. Its nominal size is 10, so it fits NG10 subplates and manifolds without adapters. A rated flow of 100 l/min supports medium-capacity actuators, while the P flow characteristic combines linear response with a fine-control zone for accurate positioning. Integrated electronics accept a 24 V DC supply and draw a maximum of 72 VA, with current limited to 1.6 A, letting designers select a suitably rated power supply. The A5 interface offers a ±10 V command input and an enable line for straightforward connection to motion controllers. Wiring is handled through a K31 connector conforming to DIN EN 175201-804, which simplifies field replacement and diagnostics.
A maximum operating pressure of 350 bar allows the valve to handle high-pressure pump circuits common in presses and molding machines. External pilot oil supply keeps pilot pressure stable even when main ports fluctuate, and internal pilot oil return eliminates the need for a separate drain line. The IP65 protection class shields the solenoid and electronics from dust and directed water jets, permitting installation on uncovered machinery. NBR seals provide compatibility with standard mineral hydraulic oils and resist swelling. The unit weighs 8.7 kg, so mounting brackets must support that static load. A time-lag 4 A fuse is required in the supply to protect the coil against short-circuit faults. The porting pattern follows ISO 4401-05-05-0-05, ensuring interchangeability with widely used base plates and facilitating quick service swaps.
