Abstract
A calibrated handknob assembly for use with a valve having a control stem, said assembly having a rising stem with spaced circumferential calibrations, a handknob having circumferentially spaced radial calibrations, a lock ring having an index cooperating with said handknob calibrations and having positions for permitting setting of the handknob 'zero' position and index position at a desired circumferential location, for placing the assembly in a condition where the handknob cannot be rotated and for permitting rotation of the handknob to change the valve opening. An O-ring is used to detent the lock ring so that inadvertent rotation of the handknob will not occur and to prevent movement of the lock ring to the position where the handknob can be removed and '0' calibration reset. The O-ring may be easily removed to permit the resetting when needed.
