PSL/PSV proportional directional spool valves, sizes 3 and 5, with MSHA approved coils, are manufactured with steel to minimize size for mining applications. Designed as a load sense valve, they control direction of motion while delivering infinite speed control for hydraulic cylinders and motors, regardless of load. They achieve a working pressure to 6000 psi, accommodate consumer flow rate to 55.5 gpm, total pump flow rate to 92.5 gpm.
