.
► The suggested safety factor for spring return actuator under normal working conditions is 30%-50%
Example:
The torque needed by valve=80N.m
The torque consider safety factor(1+30%)=104N.m
Air supply=5Bar
According to the table of spring return actuators’ output, we find output torque of SR 140K7 is:
Air stroke 0°=308N.m
Air stroke 90°=247N.m
Spring stroke 90°=180N.m
Spring stroke 0°=120N.m
All the output torque is lager than we needed.
Attention:
During the restoration,the spring return actuators’ output torque will not be affected by the imputing air from the port B. On the contrary, it will help the restoration of springs.
