A.R.I D-040 Combination Air Valve Pressure Release & Vacuum Automatic 3/4" ARI

Description: DescriptionThe D-040 series Combination Air Valve has the features of both an air release valve and an air & vacuum valve. The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of apipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs. Product FeaturesCombines the features of both an air & vacuum valve and an air release valve.Triple function:Air & vacuum component discharges large volumes of air during filling of the system.Air & vacuum component admits large volumes of air during drainage and at water column separation.The air release component releases entrapped air in pressurized systems.Dynamic design allows for high velocity air discharge while preventing premature closure.Innovative rolling seal mechanism.Materials and Corrosion ProtectionThe body is made of high-strength composite materials.All operating parts are made of specially selected, corrosion- resistant materials.D-040-C body is protected by a shell made of Cast Iron ASTM A48 CL.35B.Application RangeWorking pressure range: 0.2-16 bar.Maximum operating temperature: 60°C.Maximum intermittent temperature: 90° C.For installation:At pump stationsDownstream and upstream of shut-off valves After deep-well pumpsOn long constant-sloped pipeline segmentsAt peaks along the pipeline and at peaks relative to hydraulic gradient.Additional protective shell for anti-vandalism/theft applications.
