9.50 30 BPS - Monarch - Oil Nozzle

9.50 30 BPS – Monarch Oil Nozzle

Monarch 9.50 30 BPS oil nozzles are engineered for oil‑fired burners requiring variable firing rates with precise flow control. Manufactured to Monarch’s exacting standards, these nozzles are designed for applications where burner output must be adjusted dynamically through pressure control rather than nozzle replacement.

Technical Specifications

• Nominal Flow Rate: 9.50 GPH
• Spray Angle: 30°
• Spray Pattern: BPS – By‑Pass System (Variable Orifice)
• Rated Pressure: 100 PSI
• Manufacturer: Monarch Mfg. Works

BPS Spray Pattern (By‑Pass System)

Monarch BPS (By‑Pass System) nozzles produce variable orifice flow rates by by‑passing fluid from the nozzle swirl chamber. The effective orifice flow is regulated by controlling the by‑pass line pressure, allowing accurate modulation of fuel delivery while maintaining proper spray characteristics. This design enables smooth output adjustment across a range of firing rates without changing the nozzle, making it well‑suited for modulating burner systems.

Applications

• Oil‑fired burners with modulating or variable firing requirements
• Commercial and industrial heating equipment
• Systems utilizing by‑pass pressure control for fuel regulation
• Service replacement where Monarch BPS nozzle design and 30° spray angle are specified
