Product Name: Advantage EP Nozzle Body (Part No. 190026-4)

Description:
The Advantage EP Nozzle Body (190026-4) is the primary structural component of the cutting head assembly for extreme pressure (EP) waterjet systems, rated for operation at 94,000 PSI (approximately 6,480 bar). This precision-machined component serves as the central manifold that aligns and secures critical internal parts, including the water orifice (jewel nozzle), the mixing chamber, and the focusing tube. Its primary function is to provide a perfectly coaxial flow path for the high-pressure water and abrasive, ensuring a coherent, high-velocity cutting stream .

Applications:

• Main housing for the cutting head in EP waterjet systems .

• Aligns the water orifice with the mixing tube for optimal jet coherence.

• Provides mounting interfaces for the pneumatic on/off valve (mini valve) and focusing tube retainer.

• Suitable for cutting hard materials (metal, stone, composites) under continuous high-pressure operation.

Features:

• High-Pressure Rating: Engineered specifically for 94,000 PSI (6,200 bar) systems.

• Precision Alignment: Internal bore machined to exact tolerances to ensure perfect coaxial alignment between the water orifice and mixing tube .

• Corrosion-Resistant Construction: Machined from hardened stainless steel to withstand abrasive environments.

• Integrated Abrasive Port: Features a side inlet designed for the Venturi effect to draw garnet into the water stream .

• Durable Design: Built for long service life but considered a semi-wear component requiring periodic inspection.

Maintenance:

• Erosion Inspection: Regularly inspect the internal bore for signs of erosion, scoring, or pitting. Excessive wear will degrade cutting performance and require nozzle body replacement .

• Seal Replacement: When servicing the cutting head, always replace the O-rings and high-pressure seals that interface with the nozzle body .

• Alignment Check: Ensure retaining nuts (e.g., Gland Nut 190026-3) are tightened to manufacturer’s torque specifications to maintain proper alignment and prevent leaks .

• Mixing Tube & Orifice Care: Replace worn mixing tubes or jewel orifices as needed; damage to these parts can affect the internal bore over time .

• Full Depressurization: Before any disassembly or maintenance, fully depressurize the waterjet system and follow lockout/tagout procedures .
