Venturi Tube TypeVT
Outline
Compared with the other throttle type, this has very little pressure-loss, long life, and also, correct measurement of the flow because of no deposit in the throat portion.
In addition to the above, this type can be applied to various sizes such as small size (machine-finished one-block) and medium to large sizes (plate-fabricated).
Connection to line pipe is made by butt-welding or flange joint.
Plate-welded venturi tube (flange-joint)
Venturi tube with steam jacket
Large size plate-welded venturi tube
