Torque for actuator sizing in-lb
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 | 1.5 |
| Slurries or liquids bearing abrasive particles | 1.5÷2.5 |
