Effect of a Simulated Butterfly Valve on the Erosion-Corrosion Rate of Nickel Aluminum Bronze Alloys in Highly Turbulent Seawater
… One application involves the use of a NAB butterfly valve within a NAB fluid line to control fluid flow of seawater. Due to the chaotic environment, the corrosion rate of the NAB tubing downstream from the valve increases significantly. The disc angle at which the valve alters fluid flow …

Downhole Gas Separator Performance in Sucker Rod Pumping System
… velocity. In addition, we developed a motorized butterfly valve to reproduce the intermittent flow observed in sucker rod pumps. Experimental results show that the downhole gas separation efficiency depends on the port area and the annular area inside the separator. When ports area is smaller …

Opposing effects of recirculated gases during cranking on cold start of diesel engines
… by a CGR (Cranking Gases Recirculation) valve, without applying any back pressure on the engine. In the second method a butterfly valve is installed in the exhaust system after the turbocharger to increase the back pressure and the rate of recirculated gases. Since there is no combustion …
