KJLT series low-shearing flow control valve is a type of control valve developed by AOXIN instrument company for tertiary oil recovery process of the oil field，specially designed for polymer flow control. Because of adoption of the principle of reducing diameter to increase resistance and throttling principle of needle valve, and the structure of double cone valve core，the control valve can effectively reduce the viscosity loss of polymer，and realize the functions of low shearing and high pressure differential.
