Is there a simple formula to calculate the torque when a ball valve is operating without load? Thank you

The diameter of the valve stems varies from one manufacturer to another, so there is no universal formula that can be applied in all cases. Please send me an email and I’ll send it to you; it’s for reference only – a safety factor needs to be applied, and the actual operation still depends on the specific mold used.
