Product Overview
The Rexroth RTM 25 S2A-11/440F2H420F15V11-620 (Material Number: R901097464) is a high-performance hydraulic control block engineered by Bosch Rexroth for demanding industrial motion control systems. This assembly functions as a directional spool valve bank, integrating multiple directional control valve sections into a single compact manifold body. Each section utilizes a precision-ground spool and honed bore arrangement to direct pressurized hydraulic fluid to specific actuator ports, enabling controlled extension, retraction, and holding of cylinders or motors. The control block is designed for parallel circuit operation, allowing simultaneous actuation of multiple functions while maintaining stable pressure and flow characteristics across the system. With its robust cast-iron housing and standardized connection interfaces, this Rexroth control block serves as a central hydraulic distribution and directional control hub in mobile and industrial machinery requiring reliable, repeatable valve actuation.
