Proportional Directional Distributor Hawe Type

General  The directional spool valves types PSL and PSV serve to control both, the direction of movement and the load independent, stepless velocity of the hydraulic consumers. In this way several consumers may be moved simultaneously, independently from each other at different velocity and pressure ratings, as long as the sum of the partial flows needed for this is within the total delivery supplied by the pump. The proportional spool valves of this pamphlet are designed as valve banks and consist of three functional groups:  Basic data  Design Proportional directional spool valve according  to the Load-Sensing principle  Versions Valve bank design  Pressure pmax 420 bar  Flow Qmax 40 (60) lpm PSV 3 B 1ZM/D 200-2 -A2 H 25/25/EA/2  -A2 H 25/25/EA/2  -A2 H 10/10/EA/2  -A2 H 10/10/EA/2  -E 1-G 24   PSL Supply with pressurized oil by means of constant delivery pump (open center)  PSV Supply with pr…
