They are used for controlling the flow on production, reinjection and subsurface wellheads. Choke Valves are subjected to typical wellhead extreme conditions which can cause erosion, corrosion and other damage. Typically this can include high fluid velocity, slugging, sand production and multiphase of oil, gases and water. Also a Choke Valve has to have a very high turndown capability as it has to cover a wide range of flowrates. Thus the design of Choke Valves is required to be very robust with careful selection of valve configuration, flow path profiles, materials and ease of main...
