Full Cone Nozzles By Sahiti Engineering Works

These nozzles use a specially shaped vane placed at the nozzle inlet to give a rotational speed to the fluid flowing through the nozzle.

Because of the rotational speed of the fluid water exiting the nozzle orifice is subjected to centrifugal force and opens up in the shape of a full cone.

The extent of the angle of the cone is a function of both exit speed (created from the inlet ressure) and the internal design of the nozzle. It can vary in practice from 15A to 120A .

These nozzles can be also produced as square full cone nozzles where the square shape of the pyramidal spray is obtained by a special design of the outlet orifice.

Two important details have to be noted from the system designer when using these type of nozzles:

the spray angle is measured on the side of the square section
the square section of the spray rotates within the distance from the nozzle orifice to the target area.
