Adjustable throttle valves can be classified by their regulation methods into: needle type adjustable valve, cylinder type adjustable valve, wedge type adjustable valve, and perforated plate type adjustable valve

The valve needle and valve core are made of hard alloy, featuring wear resistance, erosion resistance and corrosion resistance

It can play an important role in regulating flow, pressure and closing

Needle-shaped structures are mainly used in oil production tree equipment, while cylindrical, wedge-shaped and orifice plate structures are mainly used in throttling manifolds
