Industrial Gate Valve, Also Known as Sluice Valve, Opens by Lifting a Round or Rectangular Gate / Wedge Out Of the Path of the
Fluid,The Valves Generally are Either Fully Open or Fully Closed, Used in Fliud Pipelines to Control The Flow of Fliud, But The Gate
Valve Should Not be Used in The Regulation or Throttling of Flow.
