Torque for actuator sizing N.m
s.6400 ISO 5211
Torque correction factors

Valve torque can vary according to operating frequency, temperature and friction characteristics of the media.
If media has more or less friction than water, multiply torque by the following factors.

Lubricating oils or liquids                                      0.8
Dry gases, natural gas, superheated steam         1.5
Slurries or liquids bearing abrasive particles     1.5÷2.5
