The importance of the small Automatic orifice in Air valves
2022-11-16By Peter Telle
VIEW MORE
Most modern combination air valves have at least two orifices, which serve three functions as follows:
●The large orifice expels large quantities of air when the pipeline is being filled. When the pipeline is full and... -
Surge Tank vs Adjustable Anti Shock - Air Valves in Water Hammer reduction
2022-11-16By Peter Telle
VIEW MORE
Surge tanks are one of the oldest of surge alleviation methods. In the past they were seen as the only reliable way to deal with surge in pipelines but air valves have come a long way since then and are now a viable alter... -

Water networks always leak.Reducing pressure during periods of low demand has long been a strategy to reduce water loss. Dual Set Pilot operated PRV with electronic controllers that set working high and low pressure by time of day i... -
Combination air valves on water transmission pipeline
2022-11-07The danger of having air pocket in Liquid pipelines is aware by most of system engineers. Issues associated with air pockets in pipelines are as follows:
VIEW MORE
● Reduced capacity of pipeline as air pockets cause flow restrictions.
● Accelerated cor... -

During the last few months of further working and testing in the air valve field, and discussed with some senior designer who also got good experience in air valve field.
Now we can make a better suggestions... -
Both pressure and flow velocity must be considered when designing reservoir level control systems.
2022-10-14By Peter Telle
VIEW MORE
Pressure considerations for reservoir inlet control valves.For reservoir level control valves, anything above 4 to 5 bar is high pressure. Pressures above 6 to 8 bar can be disastrous for control valves if precautions are not ... -
How air pockets in wastewater systems lead to corrosion and broken pipes?
2022-10-08By Peter Telle
VIEW MORE
Recent research has shown that air pockets cause extensive damage and hindrance.They reduce flow capacity and cause energy and head loss.They promote corrosion. Hydrogen sulphide is a well-known cause of corrosion in wastewater pip... -
Choosing the right check valve to prevent Waterhammer damage
2022-10-18By Peter Telle
VIEW MORE
Waterhammer destroys pipes, pumps, valves and reputations. It’s often caused by pump power failures and valves that slam shut.
The right kind of check valve can protect the pipeline and other equipment from waterhammer. Th... -
