Audited Supplier 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 highpressure gas injection/production,it has a outstanding feature that the pressure difference between inlet and outlet, as closing, can press both of the plates fast together so as to put into effect of sealing cutting, especially in the case that the pressure suddenly rises or falls, the preset sign rate of high/low pressure senor 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 valve.
