Bosch Rexroth Corporation R900900988 Hydraulic Valve

Bosch Rexroth R900900988 is a proportional directional valve that delivers precise, electro-proportional control of hydraulic flow in a 4‑way configuration. Marketed under the Rexroth catalog number 4WRAE10W60-2X/G24N9K31/A1V, the unit is driven by a 24 V DC coil and carries the Bosch Rexroth part number R900900988. This valve is designed to modulate hydraulic fluid to a connected actuator, enabling smooth ramping, accurate positioning, and variable-speed control in industrial automation or manufacturing circuits. The 4‑way architecture supports bidirectional flow to a hydraulic cylinder or motor, while the proportional electronics provide continuous adjustment of valve opening in response to an input signal, rather than simply switching between on and off states. Key verified characteristics include a 24 V DC supply, the 4WRAE family designation, and compatibility with Rexroth control interfaces such as A1V. The valve’s robust construction suits demanding environments and is selected where precise directional control is required for high‑performance hydraulic systems. Typical uses involve controlled actuation of cylinders and hydraulic motors in automation lines, presses, and material-handling equipment where repeatable, proportional responses are essential.
