The choke valve is a type of control valve which is designed to accurately control the flow rate of the wellhead and X-mas tree, in addition to regulating surface pressure in the pipeline, so that the pressure in the pipeline doesn’t affect the flow rate.

Shengji produces two types of API-compliant choke valves, i.e. a positive choke valve and an adjustable choke valve, both fitted with anti-abrasion and anti-corrosion features, and capable of meeting varied oil/gas production requirements.
