Abstract
The invention falls within the field of load sensing directional control valves and in particular it refers to an inlet section for load sensing directional control valves operating with open centre and closed centre circuit, with or without a pressure reducer valve for internal pilot pressure supply, a load-sensing signal unloader valve, a load-sensing signal pressure relief valve, while always present is a three way flow compensator (C) and the internal pilot lines; said inlet section comprises in combination a variable area damper (4), a check valve (5), a copy-spool (2) and a calibrated check valve (6).
