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.

As a professional wellhead assembly christmas tree manufacturer, Qihang supplies various types of choke valves, such as Adjustable Choke Valves, Positive/Fixed Choke Valves, Hydraulic Choke Valve, Manual or Hydraulic Orifice Choke Valves. All of our choke valves are fully designed, produced, and tested as per API 6A, API 16C, and NACE-MR0175 standards. Available in bore sizes from 1-13/16" to 7-1/16" and rated working pressure up to 15000PSI. The standard material is AISI4130 Forged alloy steel. Other specific sizes, material, and configurations are also availabe upon request.
