The HAWE PSL and PSV series are high-performance, modular, load-sensing proportional directional spool valves. They are designed to manage both the direction of movement and the stepless speed of multiple hydraulic consumers (like cylinders and motors) at the same time, completely independent of their individual loads.
The HAWE PSLF, PSVF, and SLFV (often designated as SLF) series are high-performance, modular proportional directional spool valves that operate on the load-sensing (LS) principle. They are primarily engineered for mobile hydraulics—such as cranes, construction machinery, drilling equipment, and marine technology—allowing for precise, simultaneous, and load-independent control of multiple hydraulic functions at full speed.
