Product Overview
The BOSCH 0 811 402 182 is a high-response proportional directional valve engineered for precise, infinitely variable control of hydraulic flow direction and magnitude in industrial power systems. Operating on a proportional solenoid actuation principle, this valve modulates spool position in direct proportion to an electrical input signal, enabling smooth acceleration and deceleration of actuators without the shock loads associated with conventional on/off directional valves. As a member of the Bosch proportional valve family, it serves as a critical control element in closed-loop and open-loop circuits where accurate velocity, position, and force regulation are mandatory. Its robust spool-in-body design and wet-pin solenoid construction make it suitable for demanding continuous-duty applications in plastics machinery, metallurgical equipment, and heavy industrial automation.

Engineering Features & Advantages
- Precision Proportional Metering: The spool is machined with calibrated metering notches that deliver a linear flow-to-signal relationship, enabling exact velocity control of cylinders and motors across the full stroke range. This eliminates the need for separate throttle or flow-control valves in most circuits.
- Fast Dynamic Response: The proportional solenoid and low-friction spool bore design provide rapid response to command signal changes, reducing cycle times and improving positioning accuracy in closed-loop applications.
- Integrated Position Feedback: An optional or integrated LVDT (Linear Variable Differential Transformer) continuously monitors spool position, allowing the associated amplifier card to close the position loop for repeatable, drift-free operation even under varying pressure and temperature conditions.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction and wear-resistant internal components for extended service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original BOSCH standards, allowing straightforward retrofit into existing hydraulic systems without rework.
Typical Industrial Applications
Its robust spool-in-body design and wet-pin solenoid construction make it suitable for demanding continuous-duty applications in plastics machinery, metallurgical equipment, and heavy industrial automation.
