This is the most powerful actuator series manufactured by AFC. Thanks to the double scotch yoke configuration the actuator is perfectly balanced and easy to move and match to the valve. It is available only in the hydraulic version, it can develop torques up to 1.700.000 Nm and reach less than 4 seconds operating time including time for braking.

A particular Hydraulic dumper system guarantees a rapid and controlled deceleration without sudden shocks thus avoiding water hammer and the resulting excessive pressurization of the cylinder.

It is possible to set the damper’s efficacy and point of insertion during the braking. The hydraulic communication allows the braking to be simultaneous and perfectly balanced in the two cylinders, reducing shock and vibrations.

As for every AFC actuators the part subjected to rubbing/friction are equipped with bearings and chromed surfaces.
