BM6PN-1X/08A2-12RCI

The BM6PN-1X/08A2-12RCI belongs to the BM Manifold Blocks series manufactured by Bosch Rexroth for hydraulic automation systems that distribute fluid to multiple valve locations. It is machined from Aluminum 6061-T6, a material that combines light weight with sufficient strength to handle demanding environments. The manifold supports a maximum operating pressure of 3000 psi so it can be installed in medium-pressure circuits without derating. A parallel, normal flow circuit directs pump supply evenly to each station, maintaining equal pressure across connected valves. All ports are SAE threaded to simplify hose and tube selection and to reduce assembly time. Pump and tank connections use a 7/8-14 (SAE-10) thread, providing a larger flow path for main lines, while actuator lines connect through 3/4-16 (SAE-8) A and B ports for balanced cylinder service. A 9/16-18 (SAE-6) gauge port allows technicians to attach pressure instruments for routine diagnostics without disassembling piping.

The manifold accommodates eight stations, giving designers the flexibility to mount up to eight directional valves in a single block. Each station accepts a D03 (NG6) valve, and the 2.13 in valve spacing keeps adjacent ports clear for wrench access during maintenance. Valves are held by 10-24 x 0.50 in screws, ensuring consistent clamping force across all cavities. Relief protection is provided by an Industry Common 10-2 (RCI) cavity, enabling the installation of a standard screw-in relief cartridge to safeguard the circuit against overpressure events. The block itself fastens to a machine frame or subplate with 5/16-18 x 0.45 in mounting bolts, distributing the load over a wide footprint to limit stress on the aluminum body. These combined features let the unit serve as a compact, organized hub for valve integration while maintaining straightforward service access.
