Sanitary Valve VS Ordinary Valve, What’s the Difference? When fluid control systems and product purity are important to you, standard valves simply won’t cut it. That’s where the critical choice between sanitary and general valves comes in. Understanding the difference ensures optimal performance to protect your network of stainless steel pipes and stainless steel pipe fittings.
What's the Difference? Sanitary Valve VS Ordinary Valve!
- Ordinary valves control the flow of fluids and are designed to give priority to general industrial use. It may have internal crevices which trap media.
- Sanitary valves are designed for hygiene and are designed to prevent contamination and facilitate cleaning. Well suited for use in sensitive industries.
Sanitary Valves : What Makes Them Important?
Sanitary valves have smooth, polished surfaces with no internal crevices, making bacteria less likely to grow. Minimizes product buildup.
It is designed to support automatic cleaning (Clean In Place/Steam In Place). This saves time and resources and greatly improves operational efficiency.
Materials are typically 316L stainless steel for corrosion resistance. This also applies to food, beverage and pharmaceutical production.
Many industries require sanitary design, including 3-A sanitary standards. Compliance avoids costly penalties and gives you market access to your products.
Easier cleaning means faster changeovers, which means maximizing production time.
Design and Material: Sanitary Valve VS Ordinary Valve
Design Comparison
| Feature | Sanitary Valve | Ordinary Valve |
|---|---|---|
| Internal Surface | Smooth, polished (low Ra) | Rougher, cast finish |
| Crevices/Pockets | Minimized, eliminated | Common, can trap media |
| Drainability | Self-draining, no dead legs | Variable, not prioritized |
| Connections | Sanitary Clamps, butt-weld fittings | Flanges, threaded fittings |
| Cleanability | Designed for CIP/SIP | Manual cleaning, dismantling |
| Material Contact | High-grade SS (316L), compliant seals | Various materials, often less pure |
Common Materials for Sanitary Valves
| Material Grade | Key Benefit | Typical Use Case |
|---|---|---|
| 304L Stainless Steel | Good corrosion, cost-effective | Dairy, basic food processing |
| 316L Stainless Steel | Enhanced corrosion, weldability for purity | Pharma, biotech, chemicals |
| Specialty Alloys | Extreme resistance, ultra-pure processes | Aggressive media, unique demands |
| EPDM / PTFE Seals | Biocompatible, chemical resistant | Critical sealing for purity |
Application Suitability: Valve Types
| Industry / Application | Sanitary Valve Preferred | Ordinary Valve Preferred |
|---|---|---|
| Food & Beverage | Product contact lines, processing | Utility lines, non-product systems |
| Pharmaceutical | All process lines, sterile transfer | HVAC, water treatment (non-process) |
| Biotechnology | Bioreactors, fermentation systems | General plant utilities |
| Cosmetics | Product mixing, filling | HVAC, general water lines |
| Chemical Processing | High-purity chemicals, specific processes | Standard chemical handling, utilities |
