Adjustable Choke Valve

Adjustable throttle valves can be divided into needle shaped adjustable, simple shaped adjustable, wedge shaped adjustable, and orifice plate type adjustable according to their adjustment methods.

The valve needle and valve core are made of hard alloy, which has the properties of wear resistance, erosion resistance, and corrosion resistance.

Can play an important role in regulating flow, pressure, and closing.

Needle shaped structures are mainly used for Christmas tree equipment, while cylinder shaped, wedge-shaped, and orifice plate structures are mainly used for throttling manifolds.
