The BM6PN-1X/08D2-12RCI manifold block is manufactured by Bosch Rexroth as part of the BM Manifold Blocks series and directs pressurized fluid for hydraulic automation systems. It is made from ductile iron grade 65-45-12 to withstand a maximum operating pressure of 5000 psi. The internal flow path is arranged as a parallel normal flow circuit so every valve receives an independent supply. Eight stations accept ISO 4401-03 (D03) directional valves, and a valve spacing of 2.13 in keeps the centers consistent across the bar. An industry-common 10-2 relief cavity (RCI) is machined into the body so a cartridge relief valve can be fitted directly. External connections follow SAE threaded ports, allowing standardized hoses and fittings to be attached without adapters.
The pump and tank lines terminate in 7/8-14 SAE-10 ports, while the A and B work lines are provided through 3/4-16 SAE-8 ports for balanced flow capacity. A 9/16-18 SAE-6 Ga port is included for a pressure gauge to support diagnostics. All ports fall under SAE size 12 style to maintain a consistent fitting range. The manifold mounts with 5/16-18 bolts driven 0.60 in deep, and each valve is fastened with 10-24 screws seated 0.45 in deep to hold the subplates firmly. A blackened ductile iron surface finish adds basic corrosion resistance and visual differentiation. The part number family is confirmed as BM6PN-1X/08D2-12RCI listed, ensuring compatibility with associated catalog drawings and assembly documentation.
