Orifice Choke Valve
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 used for manifold such as drilling, fracture,mud circuit,ground high pressure gas injection/production,
it has a outstanding feature that the pressure difference between inlet and outlet,as closing, can press both of the
platesfast together so as to put into effect of sealing cutting,especially in the case that the pressure suddenly rises
or flalls, the pre-set sign-rate of high/low pressure sensor can be helpful for automatic closing /shut so as to avoid
heavy accident.It is outstanding advantage that it has long working life and ability of erosion/corrosion resistance in
comparing with other choke valves.
