Hydraulic actuator control valve uses slide control and endplates and intermediate plates with endplate tapped bore for channel connections.

摘要

The thickness (D) of the endplates (50.1,50.17) exceeds the thickness (d) of the intermediate plates (50.2-50.20) and the endplates are fitted with a fixer for the actuator and/or a connector (55) for the coupled feed line (P) and/or a connector for the connecting line or again with a connector (66) for the pressure line. The specified connecting device consists of a tapped bore (68) in one endplate. The control slide (S1)(S2) is held in a hole (60,65) in the housing made up by recesses in the endplates and the tapped bore in endplate (50.1) in an actuator flange (106) surrounding the endplate recess. One end of the endplates and intermediate plates communicates via recesses together making up a pump channel (8), a tank channel and a pressure medium channel and the endplate recesses are designed as tapped bores. One endplate at least has a fixer (140) to fasten the control valve to its bearer. Prefered use is for floor-level handler hydraulics.
