Hence, it has a sharp blade either in round or in rectangular shape that is perpendicular to the material. The knife gate valves is opened and closed completely. No partial opening and closing are present. Hence, the flow is complete and no material is left behind. 

What is a lined butterfly valve? 

The lined butterfly valve is designed in such a way that its disc rotates at an angle of 90. It is either fully closed or opened. Hence, it is useful for controlling the flow of the fluid.
