In a previous blog post, we described how as a result of rising awareness about energy savings and environment protection, water supply and distribution systems need to be more efficient and be able to operate optimally at minimum pressures. While single-chamber control valves were traditionally used in these systems due to their cost-efficiency, their functionality is limited in such low pressure conditions.
Water hammer, or hydraulic shock, is a major concern in bulk water supply systems. It is even more of an issue when dealing with high pressure systems where failure may have a catastrophic impact. It is caused when fluid moving through the system is forced to suddenly stop or change direction, creating a pressure wave that can create vibration and noise, damage pumps and other system components, and even collapse pipes.
What’s the connection between control valves and smooth take-offs and landings at Berlin Brandenburg Airport?
The Berlin Brandenburg Airport is a 14.7 km2 airport that is situated 18 km south of Berlin, Germany, and is currently under construction. The 6.8-billion-euro project began in 2006 and includes two parallel runways, a six-floor passenger terminal, a 32-meter observation tower, and a museum and gift shop. The facility is designed to handle about 65 aircrafts, with a passenger capacity of up to 27 million per year. The airport is expected to open in autumn 2020.
