Determination of shaft torsion in case of butterfly valves

Determination of shaft torsion in case of butterfly valves

Determination of shaft torsion in case of butterfly valves

(OP)
Hi there,

In case of large size ( 1 metre of diameter and above ) of butterfly valves, how do you determine the torsion on the shaft?

Do you have a chart, formula or test results to determine moment on the shaft under different attack angle of the valve disk?

I am looking for this information for the butterfly valves with single disk and biplane disks. Any suggestion and help welcome.

Thanks in advance.
