API 6A Hydraulic Choke Valve

The adjustable and positive choke valves  are designed for reliable flow control and maximum wear life, The choke valves are available in flanged or threaded ends in standard bore sizes form 1-13/16" thru 13-5/8",in working pressures of 2000 psi through20000 psi.Choke ValveThe choke valve. a main component of Christmas tree,is design to control production rate of the oil well. withworking pressure up to 20000psi. Choke valves can beclassified as follows: adjustable choke  valves andpositive choke valves. By rotating hand wheel to movethe sem. the adjustable choke valve is designed to adjust the effective area available for the flow toaccomplish control of production rate. The positivechoke valve is design to accomplish control of production rate by changing flow beans.FeaturesThe coupling nut used for connecting the bonnetand body allows fast make-up and break-out.Stem tip and bean adopter are fabricated fromspecial carbide allays for corrosion and abrasionresistance.Indicator lens with scale marks allows the operatorto know stems position and actual orifice area.Turn hand wheel counter-clockwise and the valvewill open: turn hand wheel clockwise and the valvewill close.Main technical dataWorking Pressure: 2,000 psi~20000 psiNominal Bore diameter: 2 1/16"~ 7 1/16" Temperature Class: PUProduct Specification Level: 1~4Performance Requirement: PR1~2Material Class:AA~FFWorking Medium: crude oil. natural gas, drillingFluidAdjustable choke valveValve needle and spool are made of tungstenCarbide, with sufficient corrosion resistant, anti-eroding and wearable capacity.The two kinds of adjustable choke, needle typeand external sleeve type could apply to wellheads&X-mas tree and choke manifold.Positive choke valveMaterial of choke bean is fabricated from ceramicand tungsten carbide, with sufficient corrosionresistant. Anti-eroding and wearable capabilityIt adopts union bonnet so as to change chokequickly.It has application in wellhead & X-mas tree andchoke line.  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
