Bosch Rexroth R900511440 Hydraulic Solenoid Valve

Bosch Rexroth R900511440 is a solenoid‑operated hydraulic directional valve configured as a 4‑way, 2‑position unit (model designation 4WH6D53) with coil code S0131. This valve directs hydraulic flow to switch a double‑acting cylinder between two operative states, routing pressure to one work port while returning fluid from the opposite port. The R900511440 part number uniquely identifies this exact configuration within Bosch Rexroth’s valve family, ensuring compatibility with Rexroth manifolds and common hydraulic control layouts found in industrial machinery. The S0131 coil designation specifies the electrical actuation component that enables remote or automated control from PLCs and other control systems. Typical applications include automated clamping and positioning, machine tool cycles, and pick‑and‑place or indexing sequences on presses and assembly lines where reliable directional control of hydraulic actuators is required.
