Product Overview
The PUTZMEISTER PSUP 41/400-3 (Part No. 254880005) is a high-response proportional directional spool valve engineered for precise, electro-hydraulic control of flow direction and magnitude in demanding industrial hydraulic circuits. Manufactured to Putzmeister OEM standards, this valve utilizes a hardened, precision-ground spool within a close-tolerance bore, actuated by a proportional solenoid to deliver infinitely variable metering of hydraulic flow proportional to the input electrical command signal. Unlike on/off directional valves, the PSUP 41/400-3 enables smooth acceleration, deceleration, and velocity profiling of actuators, making it a critical control component in Putzmeister concrete pump boom and delivery systems as well as other heavy-duty proportional control applications. Its robust construction and spool-in-body design ensure minimal internal leakage, excellent repeatability, and long service life under continuous industrial duty cycles.

Engineering Features & Advantages
- Precision Proportional Metering: The hardened, precision-ground spool and matched bore deliver infinitely variable flow control proportional to the electrical command signal, enabling accurate velocity and position control of hydraulic actuators with minimal hysteresis and excellent repeatability.
- High-Response Solenoid Actuation: Fast-acting proportional solenoid provides rapid spool positioning and smooth directional transitions, reducing shock loads and improving cycle times in dynamic hydraulic systems.
- Low Internal Leakage: Close-tolerance spool-to-body fit minimizes bypass flow, maintaining circuit pressure integrity and improving overall system energy efficiency.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, including high pressure, elevated temperatures, and contaminated environments typical of mobile and stationary hydraulic systems.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Putzmeister OEM standards, ensuring drop-in replacement without modification to manifolds, piping, or control electronics.
Typical Industrial Applications
This proportional directional spool valve is ideally suited for Putzmeister concrete pump boom control, delivery line sequencing, and outrigger positioning systems. It is also deployed in plastic injection molding machines requiring
