Air valves are normally required on piping systems, for example, offshore fire fighting systems, to vent air from a pipeline/riser on pump start-up and admit air back into the system under vacuum conditions. Often they are overlooked, yet play a crucial role within a pipe/pump system. It is important that they are correctly specified with their function, size and location to help in ensuring that the system is operating efficiently.
For example, the system may have a fast start pump, which air valves do not like due to the fast approaching, possibly damaging water column. The fitment of an adjustable throttle device to control the air velocity through the air valve would be proposed. Working with a consultant or client is this area is an important part of the system design.
Avarus Valves Ltd is a company that specialises in the manufacturer of specialist air valves for the petrochemical industry.
Due to the severe environments associated with offshore applications, sea water service, or indeed any other arduous environment, we make these air valves in a wide range of materials including Super Duplex, Titanium, Duplex, Stainless Steel, 6Mo Hastelloy®, Monel®, Vistar®, Inconel®, Aluminium Bronze and Gunmetal. As well as these materials giving excellent corrosion resistance, they can be offered with a wide range of in-depth material testing to either Norsok or individual project or client requirements.
