Hawe Hydraulics’ PSL proportional directional spool valve controls the direction of motion while delivering speed control regardless of load type and weight. Suitable for constant delivery pump systems in various mobile hydraulic applications including crane controls, the valve achieves a working pressure of up to 420 bar (6092 psi), a flow rate of 210 L/min (55 gal/min), and a pump flow rate of 350 L/min (92 gal/min). The PSL offers a valve bank or manifold mounting design and several actuation types. Available in three sizes, spool valves can be tailored to specific applications that require unequal maximum consumer flows, and several configurations of valve sections and sizes are offered.
