.75 60 BPS - Monarch - Oil Nozzle

0.75 60 BPS – Monarch Oil Nozzle

Monarch 0.75 60 BPS oil nozzles are engineered for oil‑fired burners requiring variable firing rates with precise ultra‑low‑flow control. Manufactured to Monarch’s exacting standards, these nozzles are designed for applications where burner output must be adjusted dynamically through pressure regulation rather than nozzle replacement, particularly in low‑capacity systems.

Technical Specifications

• Nominal Flow Rate: 0.75 GPH
• Spray Angle: 60°
• 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 extremely accurate modulation of fuel delivery while maintaining proper spray characteristics. This design supports smooth output adjustment across a wide firing range without changing the nozzle, making it ideal for burners requiring stable combustion at very low firing rates.

Applications

• Oil‑fired burners with modulating or variable firing requirements
• Residential and light commercial heating equipment
• Systems utilizing by‑pass pressure control for fine fuel regulation
• Service replacement where Monarch BPS nozzle design and 60° spray angle are specified
