What you will learn about Air Vacuum Valves

Where to site them

KYNETIC version includes a feature for helping locate significant high and low elevations

Different AVV types

How to choose the correct AVV type to prevent extreme pressures

Preventing issues in pump satations

Big air cushions can cause very high pressures in pumping startup

AVV types

SURGE treats different AVV responses, different ARI models have been analyzed.


SURGE no slam effect analysis


Ways to handle big air volumes.

What you will learn about Check Valves & other singular elements.

Hydraulic analysis.

Transient results. Report review . Pump combined inertia. Different pipe materials, wave speed changing with dissolved gas ratio and solids in suspension.

SURGE analysis results.

Gas volume evolution on bladder tanks.


Pressure evolution. Gas/air volume evolution in protection elements, tanks and air valves

Check valves modelling.

SURGE allows represent pressures, flows and time, when check valves initiate its run for closing

Check valves analysis.

SURGE suggest how pressures and flows go changing with time since check valves start closing

Manufacturers information.

The importance of check valves' manufacturer information in order to get realistic results

Modeling Hydropneumatics Tanks in KYPipe

Hydropneumatics tanks (hydrotanks) use compressed air to maintain the pressure in a distribution system as opposed to overhead storage tanks, which rely solely on water elevation. They are commonly smaller and less expensive than overhead storage tanks and are used to control pump cycles in raw water, potable water, and sewer systems.

Non-Reopening Check Valves

The way Pipe2016 models an “ordinary” check valve is by allowing it to open when the differential pressure across the valve reaches any positive value, even as small as +0.00001 ft of head. The reverse is also true, the valve starts closing when the differential pressure drops below zero, even very slightly

Dynamic Characteristics of Check Valves

Improper sizing of check valves results in check valve slam, a phenomenon that produces undue increase in pressure head due rapid decrease in reverse flow velocity associated with check valve closure.
