Orifice choke valve is molded of two pieces of special carbon tungsten plates with rather ability of erosion resistance, one of which rotates to alter the concentricity between the upper orifice and lower orifice of two plates so as to adjust the flow-rate of fluid or gas.
The valve is use for manifold such as drilling, fracture, mud circuit, ground high pressure injection/production, it has a outstanding feature that the pressure difference between inlet and outlet, as closing, can press both of the plates fast especially in the case that the pressure sensor can be helpful for automatic closing/shut so as to avoid heavy accident.
