Choke Valve:

The choke valve, a main component of Christmastree, is design to control production rate of the oil well,with working pressure up to 10000psi. Choke valvescan be classified as follows: adjustable choke valves and positive choke valves. By rotating handwheel todrive the stem, the adjustable choke valve is designedto adjust the effective area available for the flow to ac-complish control of production rate. The positive chokevalve is design to accomplish control of production rateby changing flow beans.

Features:

The coupling nut used for connecting the bonnetand body allows fast make-up and break-out

Stem tip and bean adaptor are fabricated from spe-cial carbide alloys for corrosion and abrasionresistance.

Indicator lens with scale marks allows the operatorto know stem's position and actual orifice area

Turn handwheel counter-clockwise and the valvewill open; turn handwheel clockwise and the valvewill close.
