Oil Wellhead Equipment Component, API 6A Adjustable Choke Valve, Positive Choke Valve

Choke valve, a main component of Christmas Tree, is designed to control production rate of oil well, with working pressure up to 20000psi. Choke valves can be classified as follows: adjustable choke valves and positive choke valves. By rotating hand wheel to move the stem, the adjustable choke valve is designed to adjust the effective area available for the flow to accomplish control of production rate. The positive choke valve is designed to accomplish control of production rate by changing flow beans.

Features:

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

* Stem tip and bean adaptor are fabricated from special carbide alloys for corrosion and abrasion resistance.

* Indicator lens with scale marks allows the operator to know stem’s position and actual orifice area.

* Turn hand wheel counter-clockwise and the valve will open; turn hand wheel clockwise and valve will close.
