Abstract
PURPOSE: To control an actuator as desired regardless of a load condition by a method wherein direction switching valves equipped with pilot type sequence valves are connected so as to form a simultaneously operating type circuit and the direction switching valves are annexed with pressure compensating valves.
CONSTITUTION: A direction switching valve 1a is provided with: load passageways 13a, 14a connecting an actuator 5a to an internal bore 11a in which a spool valve 12a is fitted; bridge passageways 16a, 17a connected to the load passageways by a movement of the spool valve 12a; a supplying passageway 15a connected with a pressurized fluid source 3; a pilot passageway 31a branched from the bridge passageway 16a; and a pilot type sequence valve 33a. A direction switching valve 1b is constituted in the same manner and both of the direction switching valves are connected so as to form a simultaneously operating circuit. Arranged between the supply passageway of this directon switching valve and the pressureized fluid source 3 is a pressure compensating valve 2 controlling a pressure in the supply passageway into a value in accordance with a maximum load acting on the actuator.
