The main characteristic of the gate valve is in its minimal obstruction of flow passage, when fully open, providing low turbulence, with an almost insignificant pressure differential. This is possible, because their sealing system (obturator) acts perpendicular to the flow line.

Usually the gate valve is used in processes where not require frequent opening and closing operations because the handling is slower when compared to other types of valves. It is not advisable to use in adjustments and strangulations because the obturators in an intermediate position, as well as offices, are subject to wear by erosion due to the sudden increase in fluid velocity in these circumstances, providing vibration and unwanted noise.
