Component Specifications

Definition
The internal flow path is a critical hydraulic component within filling nozzles or probes, designed to create a controlled, laminar flow of liquid products (beverages, sauces, chemicals) from the supply system into containers. It features specific geometries (diameter, taper, surface finish) that minimize turbulence, prevent foaming, maintain product integrity, and ensure accurate volumetric filling. This component directly impacts filling speed, accuracy, and cleanliness in automated production lines.
Working Principle
The internal flow path operates on fluid dynamics principles, using controlled cross-sectional areas and smooth transitions to guide liquid flow. It maintains consistent pressure drop, prevents air entrapment, and enables precise shut-off to achieve accurate fill volumes without dripping or splashing. The design often incorporates venturi effects or straight-through configurations depending on viscosity requirements.
Materials
Stainless steel 316L (food/beverage), PTFE-lined stainless steel (corrosive chemicals), medical-grade polymers (pharmaceuticals), ceramic-coated surfaces (abrasive products). Surface roughness: Ra ≤ 0.8 μm for sanitary applications.
