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.
