Aquaflow supply air valves into Dubai

Air management within pipelines is essential for optimal operation. Air entrapment is associated with many negative issues such as water hammer, pipeline failure, flow rate reduction, corrosion and increased energy costs. By its nature water contains approximately 2% of dissolved air together with turbulence inducing pipeline components, air within pipelines is inevitable. However correctly sized and positioned air valves are invaluable when you consider the costs associated with a catastrophic pipeline failure.

Aquaflow have recently dispatched a number of double orifice air valves for a major new wastewater pipeline currently being constructed by a specialist pipeline contractor in Dubai.

The contract was secured due to Aquaflow’s ability to comply with the demanding performance requirements, material specifications and short delivery period. The air valves supplied ranged in size from DN80 to DN200, manufactured in durable fusion-bonded epoxy coated ductile iron with corrosion resistance stainless steel internals, and featuring an innovative engineered integral surge alleviation mechanism that negates the need for unsightly external check valve that could considerably reduce performance.

Prior to dispatch the valves underwent thorough stringent inspection and full hydrostatic pressure test witnessed by a thirdparty specialist appointed by the client. This all took place utilising our specialist calibrated in-house valve testing facilities at our Woore based headquarters.

In addition to air valves for wastewater applications the Company stocks a vast range of Aquabrake® air valves for potable applications having WRAS approval. Available in both single and double orifice configuration, and stainless steel for arduous applications up to 64 Bar.

Aquaflow is the specialist valve division of T-T Pumps, a global provider of pumping and electrical control equipment. For further information on air valves or other products offered by Aquaflow please visit
