BM6SN-1X/08A2-12RCI

The BM6SN-1X/08A2-12RCI manifold block belongs to the BM Manifold Blocks series and is produced by Bosch Rexroth. It consolidates several directional control valves into a single assembly for hydraulic automation where compact distribution and streamlined plumbing are required. The block is machined from Aluminum 6061-T6, a material choice that reduces weight while maintaining corrosion resistance for mobile or industrial machinery. A maximum operating pressure of 3000 psi allows the manifold to handle common hydraulic supply lines without risk of deformation. There are 8 stations, all aligned on a 17.00 in overall length, so installers can mount eight D03 (NG6) valves in a linear pattern. Each valve seat is spaced 2.13 in apart to match standard subplate dimensions and maintain clearance for coil housings. The internal galleries follow a series circuit type, guiding normal flow from the pressure inlet through each station before returning to tank.

The porting arrangement follows the SAE standard to ensure hose and tube fittings are readily available in the field. Pressure and return are connected through 7/8-14 SAE-10 threads, while work ports A and B use 3/4-16 SAE-8 threads to link cylinders or motors. A separate 9/16-18 SAE-6 gauge port provides an attachment point for diagnostic pressure instruments without disturbing main lines. Four 5/16-18 × 0.45 in mounting holes secure the manifold block to a frame or panel, and each valve fastens to the deck with 10-24 × 0.50 in screws for consistent clamping force on the sealing surface. A relief cavity machined to the Industry Common 10-2 RCI profile lets designers insert a cartridge relief valve directly into the body to limit upstream pressure. Together these threaded interfaces and the integrated cavity simplify installation and maintenance across diverse hydraulic systems.
