Mitigating MOV stem nut failure through proper maintenance and
By A Mystery Man Writer
Description
A major problem with stem nut thread failure is that stem position is usually interpolated from the number of stem nut rotations. If the stem nut threads strip out, the stem nut will still turn but will give a false indication of position to the control room. Such a failure of control and indication on a valve could cause a critical safety or environmental incident. This paper reviews approaches to stem nut maintenance and introduces a more scientific approach to measure stem nut thread wear.
