Product catalog summary
Specifications:
The document provides specifications for hollow cone nozzles with spray angles of 15°, 20°, and 30°, suitable for pipe sizes ranging from 3/4" to 6". The flow rates are measured in gallons per minute (GPM) at various pressures (PSI), with specific nozzle numbers and orifice diameters provided for each pipe size. The materials available include brass, 316 stainless steel, PVC, polypropylene, and PTFE.
Flow Rates and Dimensions:
The flow rates range from 7.1 to 1220 GPM, depending on the nozzle and pressure. Dimensions for each nozzle size are given, including orifice diameter and approximate weight in both PVC and metal.
Design Features:
The nozzles feature narrow spray angles, high velocity, and are available with male and female connections, as well as flanged connections. They are offered in both plastic and metal alloys.
Spray Characteristics:
The spray pattern is described as a hollow cone, with a coarse and hard-driving spray. The performance of the spray angle varies with pressure, and specific data can be obtained from BETE for critical applications.
Recommendations:
For PTFE nozzles, if the operating temperature exceeds 300°F or the pressure exceeds the listed values, it is recommended to contact BETE Applications Engineering for assistance.
