BM10SN-1X/04A3-12RCS

The BM10SN-1X/04A3-12RCS manifold block belongs to the BM Manifold Blocks series manufactured by Bosch Rexroth for hydraulic automation systems. It uses a Series circuit type so flow travels through each station in sequence, which suits applications where downstream valves depend on upstream flow. A station count of 4 provides four separate mounting positions for directional control valves. Valve spacing is fixed at 3.25 in, keeping uniform center-to-center distance for consistent tubing bends and service access. The D05 (Size 10) mounting pattern aligns with ISO size-10 valve footprints, allowing direct attachment without adapters. A 13.00 in overall length defines the space required on a machine frame or inside a manifold cabinet. All ports follow the SAE straight thread standard to accept O-ring boss fittings and minimize external leakage paths.

The A/B work ports are threaded 3/4-16 (SAE-8) to carry actuator flow while maintaining compact port size. A Ga port with a 9/16-18 (SAE-6) thread offers a gauge connection for pressure checks without disrupting the main circuit. The P/T common port uses a 1-1/16-12 (SAE-12) thread to handle higher volume inlet and tank return lines. A Sun T-3A relief cavity with P in the nose is machined into the body so a cartridge can limit system pressure internally. The relief function is located in the T-port, letting excess pressure discharge directly to tank and preventing line shock. An included mounting kit supplies the bolts and seals required for fastening the block to a subplate or machine surface, cutting installation time.
