ACTO 25 to 12500 hydraulic actuators 2 General features Designed for the operation of¼turn valves (butterfly valves, ball valves, …), the ACTO series of double acting hydraulic actuators develop output torques up to 150000 Nm. The production range consists of 10 units: -- ACTO 25, ACTO 50, ACTO 100 and ACTO 200, based on rack and pinion kinematics, developing constant output torque, throughout the stroke, -- ACTO400, ACTO800 and ACTO1600 based on scotch--yoke kinematics, developing variable torque well suited for operation of ¼ turn valves of larger size with significant hydrodynamic torque....

ACTO 25 to 12500 hydraulic actuators 12 Device adjustable travel stops, purging and hand pump connection: ACTO 25 to 1600 application The ACTO hydraulic actuators are equipped, at each cylinder end, with a special device allowing the three following functions : -- mechanical adjustable travel stops on open and closed positions. The adjustment range is ± 2° for ACTO 25 to 200 actuators and ± 2,5° for ACTO 400 to 1600 actuators. These travel stops are factory adjusted during the fitting of the actuator on the valve, -- purging of the cylinder chambers, -- connection of an emergency control by hydraulic...

ACTO 25 to 12500 hydraulic actuators 13 Hydraulic connections Standard version: direct connection The oil connection is done directly onto the housing: -- ACTO 25 to 200: by means of two 1/4’’ Gas threaded ports, -- ACTO 400 to 1600: by means of two ’’ Gas threaded ports. -- ACTO 3200 to 12500: by means of two 1/2’’ Gas threaded ports. Caution : In this case, the position holding of the actuator is achieved by the oil pressure holding. If the piloting accessories cannot ensure this function, the use of a distribution plate with piloted check valves (BSP) is recommended. See below. Optional version...
