Standard ISO Flat Fan Spray Nozzle SF Series 110° - 15 (Light Green) - Code 27602
The professional-grade standard ISO flat fan spray nozzle SF series 110° - 15 (Product Code: 27602) is a high-precision fluid-dynamic component engineered for high-volume spraying operations and intensive agricultural treatments. Molded from premium acetal resin (Kematal) and coded to international standard ISO 15 - Light Green (equivalent to a 2.5 mm calibrated orifice), this nozzle is designed for large-scale field applications and tasks requiring significant output volumes. When correctly spaced along the boom rail, these nozzles yield a highly uniform spray pattern, ensuring maximum efficiency and consistent coverage across the entire working width.
Design Details and Materials Engineering (Kematal)
This technical spray nozzle is fully manufactured from high-grade industrial "Kematal" acetal resin, an advanced technical polymer renowned for its exceptional chemical stability and dimensional retention properties. This material provides the 2.5 mm orifice with outstanding structural resistance against mechanical abrasion triggered by high-volume fluid delivery, ensuring precise flow rate stability throughout its service life. The acetal matrix is chemically inert against common agrochemicals, including herbicides, fungicides, and insecticides, ensuring a durability profile far superior to standard brass components. The 110° fan layout is optimized for balanced, overlapping patterns with adjacent boom nozzles, securing consistent volume distribution without localized missing spots or chemical pooling.

Calibration Notes and Practical Field Guidelines
- Manifold Pressure Verification: Standard application volumes are calculated by cross-referencing tractor velocity (km/h) with real-time pressure. Always monitor working pressure via an inline gauge upstream of the nozzle body to account for manifold line friction losses.
- Boom Pitch and Spacing Parameters: To leverage the full 110° fan width, ensure precise nozzle spacing (typically 50 cm layout) and height adjustment to secure perfect pattern overlapping across the entire boom length.
- Orifice Maintenance: Despite Kematal's durability, insoluble residues may clog the 2.5 mm section. Clean clogged orifices exclusively via compressed air or soft nylon brushes. Never use metal wires or needles, as these will permanently scratch the orifice geometry and distort the spray pattern.
