Sanitary sampling valves are specialized fittings designed for hygienic fluid extraction in regulated industries (pharmaceutical, food/beverage, biotech). Key features include:
Zero dead-angle design to prevent microbial accumulation
PTFE/EPDM diaphragms for contamination-free sealing
Tri-clamp/threaded connections (DIN/SMS/ISO standards) for quick assembly
Body: 316L/304 stainless steel with Ra≤0.8μm polish (FDA/3A compliant)
Seals: Silicone/EPDM for ≤134°C steam sterilization
Certifications: EHEDG, GMP, and ISO 2852 for hygienic validation
Temperature: -20°C to +135°C (standard seals), up to 230°C with specialty materials
Pressure: 0-6.4MPa depending on valve type
Sizes: DN8-DN150 (1/4"-6") with customizable ports
