Product Detail

Adjustable Choke Valve

Working Pressure: 2000~20000PSI
Material Grade: AA~FF
Temperature Grade: LU
Product Specification Level: PSL1~PSL4
Performance Requirement: PR1,PR2
Brand: Wise Channel

Choke valve, a main component of Christmas tree, is designed to control production rate of oil well, with working pressure up to 20000PSI. Choke valve can be classified as follows: adjustable choke valves and positive choke valves. By rotating handwheel 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.

The features of our Adjustable choke valve

Valve needle and spool are made of tungsten carbide, with sufficient corrosion resistant, anti-eroding an wearable capacity.

The two kinds of adjustable and external sleeve type could apply to wellheads&X-mass tree and choke manifold.


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

2. Stem tip and bean adapter are fabricated from special carbide alloys for corrosion and abrasion resistance;

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

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