Load factor N/N+R is max. 25 %; the longest working cycle (N+R) is 10 minutes (course of working cycle is
shown in the figure). The highest number of closing operations in automatic regulation is 1200 cycles per hour.
Mean value of loading torque with load factor 25 % and surrounding tempe50 °C is not higher than 40 %
of maximum tripping torque M
v
.
The highest mean value of loading torque is equal to rated torque of the actuator.
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. Service life in operating hours (h)
depends on load and number of switching. Not always, high frequency of switching influences positively
accuracy of regulation. For attaining the longest possible faultless period and service life, frequency of
switching is recommended to be set to the lowest number of switching necessary for the given process.
Orientation data of service life derived from the set regulation parameters are shown in the following table.
When using reversing contactor unit the service life of actuator is 1 million starts
Service life [h] 830 1000 2000 4000
Number of starts [1/h] Max, Number of starts 1200 1000 500 250
When using reversing contactless unit the service life of actuator is 3 million starts
Service life [h] 2490 3000 6000 12000
Number of starts [1/h] 1200 1000 500 250
