A351 CF8 304 Double Orifice Air Valve manufacturer in India

Double Orifice Air Release Valve has a complex design to allow for automatic filling and draining of the pipes. The valves also facilitate air release as needed. They come in different variations, sizes and dimensions with different pressure classes. The double orifice air relief valve has a flanged connection that allows for connection with flanged end pipes. The material used for the making of double orifice valves is usually ductile iron. There are valves ranging from DN50 through DN200 and pressure numbers up to PN16. The double orifice air valve price ranges from supplier to supplier and from location to location depending on the availability and the market demand. The aerokinetic systems prevents the air from influencing the float makes it possible for the valve to not to release prematurely.

Therefore the valve closes only after all the air has left the system and the liquid has entered into the chamber. Most of the parts of the double orifice air valve pn 16 are coated with epoxy resin to avoid corrosion, wear and tear. The seals in the valve are made up of approved grades of rubbers to make sure that the valve can withstand the compression and performs better. The Cast Iron Double Orifice Air Release Valve types are also available with different material made components available. The applications are in waterways, oil and gas, petroleum and other fluid flow application systems.
