The HAWE PSL 51/170-3 -31 H 63/63 /H -31 H 63/63 /H -31 H 63/63 /H -E 1 is a premium load-sensing proportional directional control valve engineered for demanding mobile and industrial hydraulic systems. Manufactured in Germany by HAWE Hydraulik, this sectional valve assembly allows for the precise, load-independent control of actuator speed and direction. This specific configuration features a PSL 51/170-3 inlet section, three robust working sections (type -31 H 63/63 /H) with H-type spools delivering a flow rating of 63 l/min per port, and an -E 1 end plate. Designed for maximum energy efficiency and sensitive multi-axis operation, it is the ideal solution for complex hydraulic circuits requiring reliable, heavy-duty proportional control.
