Petroleum Drilling Choke Valve
Key Specifications/Special Features:
The choke valve, a main component of Christmas tree, is designed to control production rate of the oil well,with working pressure up to 10000psi. Choke valves can be classified as follows: adjustable choke valves and positive choke valves. By rotating hand wheel todrive 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 chokevalve is design to accomplish controlling 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 spe-cial 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 the valve will close.
