    Starting thrust ≥ 1,3 . F v F stř Average mean load thrust Maximum mean tripping thrust Run time N Idle time R Cycle time Course of working cycle Service life of actuators The actuator intended for shut-off valves must be able to perform at least 10,000 operating cycles C - O - C). The actuator intended for regulating purposes must be able to perform at least 1 million cycles with operation time (during which the output shaft is moving) at least 250 hours.

    Self-locking The actuator is self-locking provided that the load only acts in the direction against motion of the actuator output shaft. Self-locking is ensured by a roller arrest immobilizing the electric motor rotor even in the case of manual control. In order to observe safety regulations, the actuators cannot be used for driving transportation lifting devices with possible transport of persons or for installations where persons can stand under the lifted load.

    To extend the service life we recommend using contactless reversing unit with a minimum service life of 3 million cycles. The standard control voltage is 24V DC. It is used for output into 4 kW or 7.5 kW. The unit consists of semiconductor elements - thyristors. 6.
