Bosch Rexroth G06A4-1X/G3/8-J3 size 6 directional valve subplate

Bosch Rexroth G06A4-1X/G3/8-J3 is a size 6 directional-valve subplate, factory material number R900511297. It provides a mounting face and four main hydraulic connections P, A, B and T for a matching individual valve or vertical stack. The main connections use G 3/8 parallel BSP threads.

The published execution uses rear external connections and the standard outer-design option. The J3 option provides improved corrosion resistance, tested for 240 hours in the salt-spray test specified by DIN EN ISO 9227; this is not a service-life warranty.

The manufacturer’s May 2019 table lists a net weight of 1.1 kg and a subplate pressure limit of 350 bar. A plate rating does not establish the allowable pressure of the complete valve assembly. Confirm the complete face layout, pilot and locating holes, screw engagement and valve-specific mounting requirements before installation. Hydraulic-fluid and cleanliness requirements follow the installed components.
