Porosity
InoxFlow Porosity Valve: Precision CNC-Machined for Hygienic Performance
InoxFlow eliminates these issues by manufacturing Porosity Valves from solid stainless steel using precision CNC machining. The result is a non-porous, easy-to-clean surface with tighter tolerances, improved reliability, and consistent long-term performance.
Porosity problems often start with something you can’t see: microscopic voids in cast components.
The InoxFlow Porosity Valve is engineered to eliminate these hidden risks, delivering a dense, non-porous structure that ensures hygienic, leak-free performance and consistent product flow. Ideal for applications in food, pharmaceutical, and chemical processing, it helps maintain product integrity while meeting strict sanitation standards.
Built from fully CNC-machined solid stainless steel, the valve enhances surface finish, improves cleanability, and ensures tighter tolerances for reliable sealing and long-term durability.
If your process demands high hygiene and contamination control, choosing a non-porous valve design can make all the difference.
SO WHICH METHOD IS BETTER?
In sanitary valve manufacturing, the production method directly influences performance, hygiene, and long-term reliability. While both methods are widely used across the industry, CNC machining offers clear advantages in applications requiring precision, cleanability, and consistent quality.
CASTING
Casting involves pouring molten stainless steel into a mold to create the valve body shape.
Advantages
Lower production cost at high volumes
Complex shapes possible
Faster for mass manufacturing
Limitations (critical for hygienic industries)
Surface porosity risk
Inconsistent tolerances
More finishing required
Potential contamination traps
Less dimensional repeatability
For pharma and high-hygiene environments, these factors can impact cleanability and validation.
MACHINING
CNC machining removes material from solid stainless steel using precision computer-controlled equipment.
Advantages
High dimensional accuracy
Superior surface finish (critical for hygiene)
Reduced porosity risk
Better seal integrity
Consistent repeatability
Ideal for validation and regulated industries
Considerations
Generally higher upfront manufacturing cost
Generally longer machining time
Thanks to InoxFlow’s partnership with ValveEngineering, these limitations are not present.
CNC machining is typically preferred for pharmaceutical-grade sanitary valves, where precision and cleanability are essential.
Casting remains common across the valve industry and out competitors, but CNC machining enables a higher level of control over geometry, surface finish, and functional performance. When executed efficiently, machining provides these advantages without increasing cost or lead time, making it a strong choice for high-performance sanitary valve applications.
