High precision structure Fluid Path / Flow Channel of Piezo Jet Valve

In a piezoelectric jet valve, the fluid path refers to the internal channel structure through which the liquid glue flows from the glue inlet to the nozzle outlet. It is one of the key components to ensure accurate, controllable, and high-speed injection during the dispensing process. It is usually composed of multiple high-precision microchannels, and the material and structure must be adapted to high-frequency drive and various glue characteristics.

Core Advantages

• High-precision structure: micron-level machining accuracy ensures injection volume stability and repeatability
  Short channel design: reduces fluid retention, improves response speed and material utilization
• Modular replacement design: flow channel components can be replaced independently, reducing the maintenance cost of the entire valve and easy to clean
• Strong chemical compatibility: stainless steel, PEEK, ceramic and other corrosion-resistant materials are used, and are compatible with epoxy glue, UV glue, silver glue and other materials
• Support heating or temperature control: for hot melt glue or high viscosity materials, the flow channel can integrate heating function to maintain constant fluidity

Different types
