Precision Micro Flow Control Engineering
Multi-stage coaxial inner flow channel inside the cylindrical body forms stable laminar fluid flow, effectively eliminating liquid turbulence, dripping and inconsistent output volume during high-speed continuous dispensing. Square flange base with multi-direction threaded holes supports flexible installation on dispensing robots and fixed filling stations, realizing quick assembly and disassembly for nozzle replacement. The separable tapered copper tip features ultra-small outlet aperture to achieve ultra-micro precise liquid extrusion, while the copper base plate fits tightly with the steel cylinder to avoid fluid leakage under working pressure. Integrated solid steel valve body resists hydraulic impact deformation, maintaining stable flow accuracy for long-cycle continuous dispensing operations.
Dual Composite Material Performance Advantages
The matched combination of stainless steel and red copper balances structural pressure resistance and heat conduction fluid stability:
- SUS304 Stainless Steel Valve Body: High structural compressive strength, complete resistance to chemical corrosion from glue, solvent and reagent liquid; non-polluting metal material compliant with medical and food-grade production standards
- C11000 Pure Copper Tapered Nozzle Tip: Excellent thermal conductivity to balance liquid temperature and prevent viscosity fluctuation; smooth polished inner surface reduces fluid adhesion and residue buildup, simplifying equipment cleaning
- Interference positioning fit between copper nozzle and steel flange ensures zero fluid leakage under high working pressure, matched thermal expansion avoids assembly gap deformation caused by temperature changes Ideal for electronic glue dispensing, medical reagent filling, cosmetic liquid injection and food micro-dosing automation equipment.
