Hago 13.50 Gallon Per Hour 80 Degree BPS Bypass Nozzle (135080BPS)Hago 13.50 GPH 80 Degrees BPS Nozzle (Spray Pattern Is Semi-Solid)Old Hago Part Number 60445Rating and TolerancesFlow rates: +/-5% from nominal rating at 100 psi, (~7 bar) operating pressure, with by-pass valve closed.Spray angles: +5 Degrees /-0 Degrees from nominal rating at 100 psi operating pressure, with by-pass valve closed.Test fluid: viscosity 35 SSU (2.7 cSt) at 100 Degrees F.Specific gravity: 0.825Type 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 simplexatomizing 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 and FeaturesCommercial and industrial combustion.Accurate, predictable flow rates.Less than 5 Degrees fluctuation in spray angleTurn down ratios between 3:1 and 4:1.Variable flow rate with a constant supply pressure.Fine atomization over entire flow range.Flow
