Wa′ter-check valve.

（Steam-engine.) An automatic valve for controlling the supply of water delivered to the boiler by the feed-water pipe. See check-valve.

In the example, a portion of the liquid is always inclosed in the annular space surrounding the disk a, which in falling to its seat is prevented from coming immediately in contact with the metal, the water acting as a cushion. The disk and seat therefore are not distorted by hammering, and the valve is almost noiseless in its action.
