Hawe PSLF, PSVF and SLF Proportional Directional Spool Valves

Hawe PSLF, PSVF and SLF valves are proportional directional spool valves, controlling the direction and velocity of flow in individual or multiple hydraulic consumers actuated simultaneously. Control is continuous and independent of the load.

The PSLF type is suitable for constant pump systems. Meanwhile, type PSVF is designed for variable pump systems with a pressure/flow controller – both are available as an individual manifold mounting valve or in the valve bank. Volumetric flows and load pressures for the individual consumers can be individually adjusted. The directional spool valve can be adapted to deliver different control tasks simultaneously, whilst operating at full speed. The valve design, with rear side ports, permits easy access during servicing, even in tight installation spaces. All sizes can be combined with each other and flange design can be combined across all sizes with fast valve replacement

Hawe PSLF, PSVF and SLF valves are suited to use in mobile hydraulics industries.
