ABSTRACT:
A safety device including a valve comprising a valve disk mounted on a rotatable shaft and movable axially toward and away from a valve seat. The shaft is rotatable by means of a geared transmission driven by a turbine wheel which is rotated by water flowing through the device. The pressure of water flowing through the device urges the valve disk toward the valve seat, but the disk and seat do not engage until the disk has rotated through a predetermined angle corresponding to a predetermined volume of water flow through the device.
