Type 505 Double Acting - Sizing
Sizing - Double Acting Actuators
The suggested safety factor for double acting actuators under normal working conditions is 20% - 30%.
Example:
• The torque needed by valve = 100 Nm.
• The torque considered safety factor (1 + 30%) = 130 Nm.
• Air supply = 5 bar.
According to the output torque table on double acting actuators the smallest model we can choose is Model 105.
