Proportional directional valves
PSL (for fixed-displacement hydraulic systems) and PSV (for variable displacement) proportional directional spool valves accommodate flows to 63 gpm and pressures to 6090 psi. Manual, hydraulic piloted, or electro-hydraulic actuation provides a high degree of proportional control for precise positioning and high maneuverability of mobile equipment. Load-sensing feature provides optimal utilization of the installed power.
