SIzing Example for Double-actlng Actuator

* Published ball valve torque= 200 Nm

* Operating medium= non-lubricated steam

* Safety factor=200Nm+25%=250Nm

* Air supply pressure available =5 bar

* The double acting actuator that produces a minimum of 250 Nm at 5 bar is the DR0O300 of 277 Nm according to the output torque table of the DR

actuator.
