Hago 5.50 Gal 60 BPS Nozzle (55060bps, 60297)

Type BPS by-passing nozzles are designed to produce variable flow rates using a single nozzle. The flow of oil into the swirl chamber of the nozzle is by-passed through a return flow orifice in the nozzle distributor (disc) and a fraction of the flow is returned to the storage tank. When the by-pass valve is closed, the nozzle acts as a simplex atomizing nozzle at its rated capacity. As the by-pass valve is opened, flow through the nozzle orifice is reduced with the balance of the oil returning to the tank. - Application: Commercial and industrial combustion. - Materials/Construction: Body and disc: Type 416 Stainless Steel. Stem and adapter:brass. Strainers: 120 mesh, 304 s.s. up to 10 gph 60 mesh, 304 s.s. over 10 gph - Rating and Tolerances: Flow rates: +/-5% from nominal rating @ 100 psig operating pressure, with by-pass valve closed. Spray angles: +5 Degrees /-0 Degrees from nominal rating @ 100 psig operating pressure, with by-pass valve closed. Test fluid: viscosity 35 SSU, specific gravity .825 @ 60 Degrees F.Features: Accurate, predictable flow rates due to linear and uniform relationship between by-pass pressure and orifice flow. Less than 5 Degrees fluctuation in spray angle over entire operating (turn down) range. Turn down ratios between 3:1 and 4:1 Variable flow rate with a constant supply pressure Fine atomization over entire flow range. Flow curves and data for each
