Produced to Monarch’s exacting standards, these nozzles support consistent flame development and efficient operation in light‑ to medium‑capacity heating applications where a narrow spray angle is specified.

Technical Specifications

• Flow Rate: 4.00 GPH
• Spray Angle: 30°
• Spray Pattern: PLP – Semi‑Solid Cone
• Rated Pressure: 100 PSI
• Manufacturer: Monarch Mfg. Works
• Pack Quantity: 12 nozzles

PLP Spray Pattern (Semi‑Solid Cone)

Monarch PLP (Semi‑Solid Cone) nozzles are designed for larger firing capacities, covering a flow range of 2.25 to 100.00 USGPH. The PLP series provides fine atomization with a solid cone spray pattern at lower capacities (up to approximately 3.50 GPH), then gradually transitions toward a more hollow spray pattern as flow rates increase. This progressive spray characteristic supports stable flame development, improved fuel‑air mixing, and controlled flame expansion as firing rates increase.

Applications

• Residential and light commercial oil‑fired burners
• Boilers and furnaces requiring moderate GPH output
• Installations specifying a 30° spray angle and Monarch PLP spray pattern
