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.
Producing air valves for the global oil and gas, petrochemical, marine and water utility industries, Avarus Valves is committed to providing all of your air valve requirements.
Manufactured in the UK, we make air valves in various materials that give excellent protection in the severe environments associated with offshore applications, seawater service or indeed any other arduous environments. These materials include super duplex, titanium, duplex, stainless-steels, aluminium bronze, gunmetal, Hastelloy®, Monel®, Inconel® and various other nickel alloys.
As with many modern-day projects, specific material testing and documentation are a vital part of a contract. Our air valves can be offered with a wide range of detailed material testing to meet each project requirement. We normally use UK foundries or UK/EU certified materials that are Norsok M-650 / TR2000 approved.
Regardless of material and quantity, Avarus Valves endeavours to find suitable solutions for specific demands or special circumstances. We can manufacture our air valves on short delivery times if needed.
We are also ISO9001: 2015 and ISO14001: 2015 UKAS accredited and Achilles approved.
Air valve functions
We produce air valves with various functions, such as air release (small orifice); air vent and vacuum (bi-function); air release, vent and vacuum (tri-function); and can custom-build to fine detail with options such as a variable throttle device to give adjustable venting control, inflow and outflow check device for one way air flow and flanged outlet for piping away facility.
Butterfly, ball, check valves and strainers
With experience in successfully supplying to multi-national companies, our innovative character and expertise enables us to also supply associated valves, such as exotic material gate, butterfly, ball, check valves and strainers. These can be used for isolation of the air valves or individual use.
