Product Overview
The Rexroth R961011849 (catalog designation -29/STW0280-10/-E) is a high-performance directional spool valve engineered for precise control of hydraulic fluid flow direction, distribution, and pressure in demanding industrial circuits. As part of the Rexroth STW series, this valve utilizes a robust spool-and-sleeve design that ensures minimal internal leakage, fast response, and reliable switching performance. It serves as a critical control element in hydraulic power units, manifold blocks, and centralized lubrication or actuation systems, directing flow to cylinders, motors, or other actuators with high repeatability. The valve is designed for direct OEM replacement and is fully compatible with standard ISO 4401 mounting interfaces, making it a versatile solution for both new installations and maintenance retrofits.

Engineering Features & Advantages
- Precision Spool Metering: The hardened, precision-ground spool and sleeve assembly ensures accurate flow metering, minimal pressure drop, and consistent response across the entire operating range.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction that resists contamination and extends service life in high-cycle applications.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, including port patterns, mounting holes, and electrical connections, ensuring drop-in replacement without modification.
- Low Internal Leakage: Tight spool-to-sleeve clearances minimize bypass flow, improving system efficiency and reducing heat generation in holding circuits.
- Flexible Circuit Integration: Compatible with a wide range of hydraulic fluids and can be integrated into manifold blocks or used with subplates for simplified piping.
Typical Industrial Applications
This Rexroth directional spool valve is widely used in plastic injection molding machines for mold opening/closing and ejection control, metallurgical presses for directional force application, CNC machine tools for tool clamping and pallet changing, and general industrial hydraulic power units requiring reliable directional flow control. It is also suitable for construction and marine hydraulic systems where precise actuator direction and holding performance are critical.
