NFH
NFH
Tungsten carbide orifice inserts are used for maximum wear resistance and service life. The connections are male, with sizes available in 1/4” NPT and BSP (R).
The spray produces relatively coarse atomization with a uniform distribution and tapered edges, suitable for overlapping sprays. The spray pattern is a flat fan, with angles ranging from 5° to 120°. The flow rate varies from 0.012 to 4.33 gallons per minute (gpm).
The document provides detailed specifications for various nozzle numbers, including K factors, flow rates at different PSI levels, equivalent orifice diameters, available spray angles, and weights in ounces. For example, the NFH-0.18 nozzle has a K factor of 0.0012 and a flow rate of 0.012 gpm at 100 PSI, with available spray angles from 5° to 50°.
The standard materials used include tungsten carbide inserts and 303 stainless steel housing.
The flow rate in gallons per minute (GPM) is calculated using the formula: Flow Rate (GPM) = K √ PSI. Spray angle performance varies with pressure, and BETE should be contacted for specific data on critical applications.
