Forward Flow:
As fluid progresses in the forward trajectory, the resultant pressure propels the valve disc away from the valve seat, thereby unsealing the valve and facilitating fluid passage.
Reverse Flow:
Conversely, in the event of fluid backflow, the valve disc, influenced by its weight, spring force (if present), and the counteractive pressure of the backflowing fluid, promptly resettles onto the valve seat, effecting valve closure and thwarting reverse flow.
