Hydraulic fluid flow control valve for e.g. hydrostatic profiled rail guide, has adjusting part to adjust control characteristics of controller and with operating section accessible from outside of pipe to adjust another adjusting part

摘要

The valve (11) has a discharge opening (18a) and an inflow opening (18) for hydraulic fluid. A differential pressure controller (17) is provided for pressure independent supply of a constant volume flow of the hydraulic fluid. An adjusting part (15a) adjusts control characteristics of the differential pressure controller. The adjusting part has an operating section (27), which is accessible from outside of a hydraulic pipe, for adjusting another adjusting part (26).
