HAWE North America Inc. Proportional Directional Spool Valve PSL 3

The directional spool valve bank type PSL/PSV consists of directly attached valve sections. Type PSL is designed for constant delivery pump systems (pressure/flow controller) whereas the type PSV is for variable displacement pump systems. Both are available in three sizes. They serve to control the direction of motion and provide infinite control of the speed of motion of hydraulic consumers regardless of their load. Several consumers may be operated simultaneously and independently of each other. The main field of application is mobile hydraulics (e.g. crane controls etc.). These valve banks can be tailored to a specific application, requiring unequal max. consumer flows at port A and B as well as additional functions (e.g. secondary pressure limitation, functional cut-off) which can be incorporated in the basic valve, the intermediate plate, or the ancillary block.
