JLK,JLG series throttle valveDetailed product description：

The design of JLK and JLG series throttle valves complies with the requirements of SY/T5127-2002, API Spec 6A, and API Spec 16C. They can be divided into adjustable throttle valves and fixed throttle valves according to their structural forms. The fixed throttle body and adjustable flow valve body can be interchanged. According to the principle of action, it can be divided into manual throttle valves and hydraulic throttle valves. The valve cover and valve body are metal to metal sealed. The fixed throttle valve nozzle, adjustable throttle valve stem, valve core, and valve seat are all made of hard alloy, which has the characteristics of wear resistance, erosion resistance, and reliable operation. According to their functions, they can be divided into needle shaped adjustable flow valves and cylinder shaped adjustable flow valves. Needle shaped adjustable flow valves are mainly used for oil (gas) volume regulation in oil (gas) wellhead equipment; The cylindrical adjustable flow valve is mainly used for throttling and killing well manifolds, controlling the fluid casing pressure inside the well.
