Manually or mechanically controlled hydraulic distributor 03PF40 is designed for distribution and control of work flow between generator (pump) and executive mechanisms (cylinder, hydro-motor, etc.). It has parallel action. Setting of flow rate is possible to the first spool and the remaining flow rate is used by subsequent spools.


03PF40 is a mono-block distributor. Its body is made of cast iron EN-GJL300. Spools are made of carburized steel with hard chrome plating.


The distributor is fixed with two bolts M8.
