Abstract
A regulator includes a valve body and a control element movable between a closed position, in which the control element engages a valve seat, and an open position, in which the control element is spaced away from the valve seat. A stem is operatively coupled to the control element and is axially aligned with a longitudinal axis of the valve body. An indicator assembly is at least partially disposed in the valve body and is operatively coupled to the stem. The indicator assembly includes a rod operatively coupled to the stem and an indicator operatively coupled to the rod. The indicator is arranged to display a position of the control element. The rod of the indicator assembly is movable by the stem between a first position when the control element is in the closed position, and a second position when the control element is in the open position.
