Description

Converting a switched axis into a controlled one often fails on the missing pilot ports in the existing manifold. This 4WRTE needs none, because supply and return run internally, and it controls 220 l/min nominal flow at 350 bar.

Benefits

Internal pilot routing in both directions, so the existing manifold stays unchanged.
220 l/min nominal flow, 870 l/min at peak, at 350 bar.
Internal position control of the main spool turns a switched axis into a controlled one.
Linear characteristic and 4...20 mA command for straightforward loop tuning.
17.92 kg on the standard ISO 4401-08-08-0-05 interface.

Applications

The version is intended for retrofitting positioning functions on existing presses, lifting gear and machine tools. System pressure must stay above the minimum pilot pressure at all times. HL hydraulic fluid is used, sealed with NBR.

Manufacturer

The manufacturer is Bosch Rexroth, material number R901039675.
