Product catalog summary

Specifications:
The document provides specifications for nozzles with various orifice sizes and BSPT thread sizes. The flow rate in liters per minute is given for different pressures (Bar.G.) with a typical turnover ratio of 3:1. The nozzles are available in sizes ranging from 3/8” to 3/4”.

Materials and Construction:
Nozzles are constructed from 316 Stainless Steel or Glass-filled Polypropylene (Polyglass). They feature a one-piece design with no internal components, available with male BSPT threads.

Features:
The nozzles offer high efficiency, a wide range of flow capacities, and resistance to erosion and corrosion. They have a tapered inlet to reduce wear and resist clogging, producing a high-velocity jet stream for maximum agitation and mixing.

Applications:
These nozzles are suitable for agitation and mixing of liquids containing solid suspensions, cataphoresis plants, and steam heating of liquids in tanks requiring uniform heat distribution.

Temperature and Pressure Limits:
The maximum recommended temperature is 75˚C for Polyglass and 500˚C for Stainless Steel. The maximum recommended pressure is 10 Bar.G. for Polyglass and 35 Bar.G. for Stainless Steel.

Heating Chart:
A chart is provided showing the time in minutes to heat 300 liters of water at various steam pressures using a single 1/2” BB 100 Stainless Steel nozzle with a 6.4mm orifice.
