This document provides information about the available spare parts for Bosch Rexroth products, including the types, sizes, maximum operating pressure, and maximum flow of the 2- and 3-way high response cartridge valves. These valves are controlled by a servo directional valve and the position of the control spool is monitored by an inductive positional transducer. The document also mentions some typical applications and provides information about the control electronics.
The 2WRC and 3WRC high‑response cartridge valves are 2‑ and 3‑way hydraulic valves designed for closed‑loop control of large flows. They feature servo directional pilot valves, integrated electronics (OBE) or external control options, and inductive position transducers.
The document includes functional descriptions, technical data (sizes, pressures, flow rates, weights), electrical connection information, installation dimensions, and guidelines for calibration and maintenance.

The valves are rated for a maximum operating pressure of 420 bar.
They are offered in nominal sizes 63, 80, 100, 125, and 160.
The WRCE versions use a supply voltage of +24 VDC (or +15 VDC for some models).
The 3WRC valve can handle up to 50 000 L/min.
