What should the torque value be for a 3X150LB hard-sealed ball valve? Similar to 4” x150LB

It’s generally no more than 200 N-m, right?

Floating ball: 125, Fixed ball: 150. These are theoretical values; when selecting actuators, it is advisable to apply a safety factor of 1.3, while for hard-sealed designs a safety factor of 2 is recommended!
