Proportional Directional Spool Valve for Constant-Delivery Pump Systems
Available in three sizes, PSL spool valves can be tailored to specific applications that require unequal maximum consumer flows at ports A and B, as well as additional operations including functional cut-off.
Several configurations of valve sections and sizes are available for the PSL to provide users with maximum functionality. A number of connection-block versions complete many functions, including feeding the electro-hydraulic actuation, arbitrary idle pump circulation, damping the flow controller or pump controller, and minimizing circulation back pressure.
Every PSL spool valve achieves a working pressure to 420 bar, a total consumer flow rate of 210 liters/min. and a total pump flow rate of 350 liters/min.
