Sanitary Valves – Business Overview

Definition  

Sanitary valves are purpose-built components that meet pharmaceutical-grade (GMP) or food-grade (3-A, FDA) hygiene standards. All wetted surfaces are mirror-polished stainless steel (Ra ≤ 1.6 µm) to eliminate physical and chemical hazards. They are used where the highest cleanliness is mandatory—food processing, pharmaceutical production, hospital cleanrooms, biotech fermentation, etc.

Product Range  

• Butterfly valves  

• Ball valves  

• Check valves  

• Solenoid valves  

• Diaphragm valves  

Materials & Sealing  

• Body: 304 SS or 316L stainless steel  

• Seats: stainless steel for metal-to-metal sealing, or food-grade EPDM (≤ 140 °C); fluorinated elastomers are avoided for toxicity reasons.

Mechanical-seal Requirements  

1. GMP compliant  

2. Surface finish ≥ 1.6 µm  

3. CIP/SIP compatible  

4. Smooth transitions—no product hold-up  

5. External anti-migration seal design

Sanitary vs. Industrial Valves  

Sanitary valves are engineered for sterile, corrosion-free, easy-clean operation. Industrial valves prioritize pressure/temperature ratings over surface finish and are used in petrochemical, power, metallurgy and general process industries. Only qualified sanitary-valve manufacturers may produce these products; non-compliant materials (e.g., residual lead) pose serious health risks. Buyers should source exclusively from certified sanitary-valve suppliers and avoid counterfeit goods.
