BM6PN-1X/08D2-12

The BM6PN-1X/08D2-12 manifold block belongs to the BM Manifold Blocks series manufactured by Bosch Rexroth for hydraulic automation where multiple directional valves must be grouped on a common pressure and return gallery. It uses a parallel, normal flow circuit so pump and tank lines reach every station without internal cross-porting, which simplifies troubleshooting. Eight stations are provided, allowing up to eight size 6 (D03) directional valves to be installed on one block. A valve spacing of 2.13 in keeps the assembly compact while maintaining clearance for coil housings. Each valve is secured with 10-24 x 0.50 in DP mounting screws to hold the sub-plate firmly against the sealing surface. Working lines connect through 3/4-16 (SAE-8) A and B ports that accommodate typical cylinder hoses, whereas pump and reservoir lines use 7/8-14 (SAE-10) P and T ports to manage higher flow.

Ductile iron rated 65-45-12 is used for the manifold body to resist fatigue and provide good machinability at assembly. A maximum operating pressure of 5000 psi lets the block serve in high-pressure circuits found in presses or mobile equipment. A 9/16-18 (SAE-6) Ga port is included so a test gauge can be fitted for system monitoring without extra fittings. The block fastens to a machine frame through 5/16-18 x 0.45 in DP manifold mounting threads that keep the mass stable during pressure spikes. Overall length is 17.00 in for the eight-station model, giving designers a predictable footprint when laying out control panels. All service lines share the SAE threaded style coded “12,” ensuring that standard O-ring boss connectors seal each port.
