Manual orifice choke valve
  Orifice choke valve is molded of two pieces of spe-cial carbon tungsten plates with rather ability of erosionresistance, one of which rotates to alter the concentric-ity between the upper orifice and lower orifice of twoplates so as to adjust the flow-rate of fluid or gas.
   The valve is used for manifold such as drilling,fracture, mud circuit, ground high-pressure gas injec-tion/production, it has a outstanding feature that the pres-sure difference between inlet and outlet, as closing, canpress both of the plates fast together so as to put intoeffect of sealing cutting, especially in the case that thepressure suddenly rises or falls,the pre-set sign-rate ofhigh/low pressure sensor can be helpful for automaticclosing/shut so as to avoid heavy accident. It is out-standing advantage that it has long working life andability of erosion/corrosion resistance in comparing withother choke valves.
