Page 13: Design And Principle Of Operation
The actuator is a linear actuator which is controlled by a three-step signal. Depending on the version with or without fail-safe ac- tion, it is particularly suitable for mounting on SAMSON Series 240 and 250 Valves as well as to Type 3214 Valve (DN 300 and 400). Principle of operation The electric actuator consists of a reversible asynchronous motor and a maintenance-free planetary gear with ball screw drive. -
