Product Overview
The PUTZMEISTER PSLP 41/400-3 is a high-response proportional directional spool valve engineered for precise, infinitely variable control of hydraulic flow direction and magnitude in demanding industrial circuits. As a pilot-operated proportional valve, it modulates spool position proportionally to an electrical input signal, enabling smooth acceleration, deceleration, and load-holding behavior in actuators. The PSLP series is widely deployed in Putzmeister concrete pump systems and other heavy-duty machinery where accurate flow metering, low hysteresis, and repeatable positioning are essential. This valve functions as the central control element between the hydraulic power source and the actuated load, delivering metered flow to cylinders and motors with high dynamic fidelity.
