Orifice choke valve
Brief introduction:
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.
Application:The valve is used for manifold such as drilling ,fracture,mud circuit,ground high--pressure gas injection/production.
Advantages:It has long working life and ability of erosion/ corrosion resistance in comparing with other choke valves.
