To divert the flow of backfill material from one point of placement to another. Furthermore, to ensure that the placed backfill material is not diluted or washed away by the flush water, the valve can be switched to divert flushing water away from the placement point at the end of a backfill placement cycle.

To allow air to be admitted into the pipe (pump out column) if a sub atmospheric condition (vacuum) develops due to a pump trip out.
To destroy pressure energy in fluids so that the energy can be reduced by a finite desired amount.
To minimize pipeline pulses (water hammer), generated by a pump trip out, by closing rapidly in the reverse flow direction. It is mainly used with Pump Control Valves in mine dewatering applications.
