Hawe PSLF and PSVF Proportional Spool Valves


Hawe PSLF and PSVF valves are proportional directional spool valves. They control the direction of movement and the velocity of hydraulic consumers (individual or multiple) actuated simultaneously. Control is continuous and independent of the load. At full speed, the operation of several functions can be completed at once. These valves are specialised for extremely high flow rates.

The PSLF type is suitable for constant pup systems. Meanwhile, the PSVF type is suitable for variable pump systems with a pressure/flow controller. Both versions are available as an individual manifold mounting valve or in the valve bank. Volumetric flows and load pressures for each individual consumer can be individually adjusted. The directional spool valve can be adapted to different control tasks, and all sizes can be combined with each other. Connections on the rear enable easy access to the valve for servicing, even in tight installation spaces.

The proportional directional spool valve type PSLF and PSVF is used in mobile hydraulics, in particular in crane and lifting equipment, construction and mining machinery, drilling equipment as well as in offshore and marine technology.
