Air Control Slide 2″ 6″ Slide Wafer Cast Steel Knife Gate Valve
Gate valves are used to shut off the flow of liquids rather than for flow regulation. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance. The size of the open flow path generally varies in a nonlinear manner as the gate is moved. This means that the flow rate does not change evenly with stem travel. Depending on the construction, a partially open gate can vibrate from the fluid flow.Including the Electric Knife Gate Valve, Flsmidth-Krebs Knife Gate Valve,Gear Operated Knife Valve,Heavy Duty Knife Gate,Lug Knife Valve, Slurry Knife Valve and Stainless stell Knife Gate Valve,etc.
