Full Cone Wide Square B4

Type B4 nozzles use an internal swirl plate to give a uniform full cone spray pattern with a wider 120 degree spray angle. The aperture is modified to give a square pattern.

Rated flows are from 5.6 L/ minute to 880 L/ minute; operating pressures from 0.75 Bar to 7 Bar; spray angle 110 degrees. Thread connections from 1/4″ to 1″ BSPT male and 3/4″ to 2″ BSP female. Material: brass or stainless steel AISI grade 303.

Large capacity types F-B4 are cast stainless steel AISI grade 316 with machined threads.


Installations with many nozzles in which the square spray provides a better coverage.

To order: specify the thread size and type, nozzle code, capacity code or flow rate and operating pressure, and material – eg 1/4 MB4-14s.
