Abstract
An assembly for and part of a slam-shut safety device. The assembly includes a reset pin and a valve disc operatively connected to the reset pin, the reset pin and the valve disc being movable between a first position, in which the valve disc is adapted to be spaced from a slam-shut valve seat of the slam-shut safety device, and a second position, in which the valve disc is adapted to engage the slam-shut valve seat of the slam-shut safety device. The assembly also includes a reset pin assembly including a reset rod operatively connected to the reset pin, and a reset sleeve arranged to support an end of the reset rod. The assembly further includes a feedback system arranged proximate the reset pin assembly and configured to provide data indicative of whether the reset pin and the valve disc are in the first position or the second position.
