The vortex valves limit the flow in the piping system, using the pressure head on the inlet side. Submerged vortex valve with a continuously adjustable inlet. A tie rod between the vortex valve and the manhole opening allows the valve to be removed for cleaning or maintenance. A manhole cover must be placed above this tie rod.
