Self actuated Pilot Operated Water Control Valves are very flexible in that they can be used to do many functions and a combination of functions. It is not uncommon to have combinations such as Pressure Reducing and Pressure Sustaining on one valve. The other beauty about this type of valve is that as long as…
DetailsSmall pressure reducing valves have long been used to control the pressures into the glands of slurry pumps. Multi-stage pumps need several pressure reducing valves, each set differently. We bump into problems with this approach: Pressure reducing valves can be adjusted – people set them incorrectly. Increased demand from one gland (perhaps because of a…
DetailsIn part 1 of this article we looked at the use of check valves to reduce waterhammer. Today we’ll examine at how surge relief valves, air valves and surge tanks can be used to prevent waterhammer damage. Surge relief valves Surge relief valves open to allow the high pressure spikes caused by waterhammer to vented,…

Ultra has been involved with the Presenting of a high level Surge Seminar covering all aspects of Water Hydraulics, the analysis of Transient flows and the reduction of Water hammer causing events, in conjunction with one of its Principals (ARI Flow Control).…
DetailsWaterhammer 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. The wrong kind causes it. Check valves are generally installed on pump delivery manifolds to prevent return flow. Their performance doesn’t…
