Description A.R.I. D-050 is a reduced bore Combination Air Valve Series. Installed on liquid transmission systems, the Air Valve is designed to improve hydraulic operation by protecting the pipeline, increasing pipeline efficiency and reducing energy requirements. Benifits Easy to install and maintain, reduces downtime High-capacity air discharge, no premature closure Reduces water hammer impact Saves energy and increases system efficiency Long-term maintenance-free operation Screen protected outlet that prevents intrusion of insects and debris Non-corrosive and durable Leak-free sealing over a wide range of pressure differentials Automatic air release valve orifice that allows for high flow air release, lessens obstruction by debris Installation Guidline Pump stations: downstream of the pump and the check valve Downstream and upstream of shut-off valves Downstream of deep-well pumps On long constant-sloped pipeline segments At peaks along the pipeline and at peaks relative to hydraulic gradient At end lines Before water meters On strainers and filters Municipal and industrial water conveyance systems Specifications 0.2 - 16 bar Maximum working temperature: 60° C Maximum intermittent temperature: 90° C Connection type: Threaded male BSPT(2”)
