Application of gate valves

Gate valves are the most widely used of all types of valves in modern industry. In these valves,a gate -like plate in the valve body moves vertically with the fluid between matching seats to open or cut the flow path.Use it as cut-off,and in the full open the entire flow channel through,at this time the media operation pressure loss is the minimum.General type gate valves are normally apply to don’t need to often open /close,and keep the gate of full open or full close work occasions it is not suitable for use as adjust or throttling for high-speed flow medium,ram in local open condition can cause the vibration of the valve,and vibration and possible damage of disc and seat sealing surface,and the throttling can make gate medium of erosion.
