The actuators of this series are complete of chromed steel piston rod and painted steel body.
Each actuator is made up of two unbalanced cylinders which can be installed as a couple on the same rudder (for instance for single rudder vessels), or separately on each rudder (in case of double rudder vessels with mechanical connection/tie bar).
The cylinders of this series are very strong and are especially recommended for working boats and/or for medium and big M/Y.
These cylinders are also produced in special version with internal limit switches bypass valves which can be used for safety reasons but also on vessels which do not have the possibility to have a tie bar installed in case of double rudder (ex: Catamarans). The bypass valves allow a more efficient synchronization of the rudders at the end of the stroke with the addition of a special valve called V.E.I.S.A.
