ENNACTO 200 to 12500 2 General features Designed for the operation of ¼ turn valves (butterfly valves, ball valves, …), the ENNACTO series of single acting hydraulic actuators with gas cartridge (Nitrogen) develop output torques up to 125 000 Nm. The production range consist of 7 units: -- ENNACTO 200, ENNACTO 400, ENNACTO 800 and ENNACTO 1600, based on scotch--yoke kinematics, -- ENNACTO 3200 , ENNACTO 6400 and ENNACTO 12500, based on rod and crank kinematics. The energy accumulator is a compressed gas cartridge (Nitrogen). In the standard version, these actuators are hose and fine dust proof...

ENNACTO 200 to 12500 4 Operation ENNACTO 200 to 1600: yoke and slide kinematics The yoke and slide kinematics develops variable output torque very well suited to the operation of¼turn valves with hydrodynamic torque. The movement transmission is achieved by means of the piston system .., the slide operating nut .., the rolling pad .. and the yoke ... The translation of the piston .. secured by the pressure in the actuator cylinder causes the linear travel of the operating nut ... This movement drives the sliding of the pads .. in the 2 slides of the operating nut .. and allows the rotation of...

ENNACTO 200 to 12500 6 ENNACTO 3200 to 12500: Rod and crank kinematics The rod and crank kinematics develops variable output torque very well suited to the operation of ¼ turn valves. The translation of hydraulic actuator .. causes the translation of arm ... This translation movement is converted into a ¼ turn rotational movement of chuck .., integral with the valve shaft. This conversion movement is effected via the connecting rods whose length defines an exact and invariable position of the chuck during the closing operation. The control fluid pressure ensures at once the valve operation and...
