A new scaled-down proportional spool valve from Koppen + Lethem offers more than 50litre/min at 420bar and features the same functionality as larger models. Smooth positioning and load-independent motion control have been standard for the well-established Hawe proportional spool valves, type PSL/PSV. This new size is a scaled-down version with more than 50litre/min at 420bar that features the same functionality. Its exceptionally compact design introduces two real advantages: it takes up less space in the hydraulic system at much reduced cost. The size 2 broadens the range of applications and markets that are already covered by size 3 and 5. Typical applications include truck-mounted cranes, municipal trucks, lifting devices, logging equipment and concrete delivery booms.
