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.

The Surge Anticipation Valve (SAV) is designed to prevent pressure surges above the steady state pumping pressure in the event of a pump trip out, entirely by mechanical means, thus eliminating the need for electrical systems that require a battery UPS back-up.
The high pressure Excess flow valve is designed to shut off in the event of an excess flow condition resulting from a pipe burst or in circumstances where maximum flow rates need to be controlled. This must be done without causing a pressure surge (water hammer) in the process. The trip mode is in 2 stages – initially very rapid to prevent runaway flow, then slowly to give a soft shut off. The trip flow is normally set at 35% above the working flow rate.
The Water Level Control Valve, is used to control the level of water in underground dams. The valve is typically coupled to a Manual Isolation Valve and an Energy Dissipator to form a system which will maintain dam water levels.
