Abstract
In a valve having a valve body and a bonnet mounted on the valve body, a bonnet lock secures the bonnet against relative rotation with the valve body. The bonnet lock cooperates with a pin driven into the valve body to lock the bonnet against rotation. Unequally spaced slots formed about the lower end of the bonnet lock permit adjustment of the bonnet lock for alignment with the lock pin. A jam nut threadably mounted on the bonnet engages the bonnet lock and maintains it in position.
