API-6A Wellhead Christmas Tree Adjustable Choke Valves

A Choke Valve is a very important part of Wellhead Christmas Tree and Choke Manifold. It is a type of control valves, mostly used in Oil & Gas production wells to control the flow of well fluids being produced. Another purpose that the choke valves serve is to kill the pressure from reservoir and to regulate the downstream pressure in the flowlines. Choke valves allow fluid flow through a very small opening, designed to kill the reservoir pressure while regulating the well production. The reservoir fluids can contain sand particles, therefore the choke valves are usually designed to handle an erosive service. Typically Oil & Gas producing wells have two choke valves in series, one non-regulating choke valve (Positive or Fixed) and one regulating choke valve (Adjustable) downstream to the non-regulating choke valve.
