Why Choose an SS316 Single Disc Wafer Check Valve?
In pharmaceutical and dairy processing, fluid purity and system cleanability are non-negotiable. The SS316 Single Disc Wafer Check Valve is specifically engineered to meet these stringent requirements. SS316 (CF8M) provides superior resistance to the aggressive cleaning chemicals (caustics and acids) used in daily Clean-in-Place (CIP) cycles, while the molybdenum content prevents pitting corrosion from chlorinated water and sanitizers.
The single disc design offers a distinct advantage over dual-plate check valves in food and pharma: it features a lower cracking pressure and a more uniform, streamlined flow profile. This minimizes pressure drop and eliminates the central hinge pin cavity found in dual-plate designs, ensuring zero product trapping and preventing bacterial harborage points.
Hygienic Design of the SS316 Single Disc Wafer Check Valve
Crevice-Free Construction
The valve body and disc are precision-machined to eliminate dead legs, sharp corners, and crevices. This ensures that viscous products like milk, cream, or pharma suspensions flow smoothly without residue buildup.
Mirror Polished Internals
Standard internal surface finish of Ra < 0.8 µm (electropolish available on request). This ultra-smooth finish prevents microbial adhesion and biofilm formation, critical for GMP compliance.
CIP & SIP Ready
Fully compatible with Clean-in-Place (CIP) and Sterilize-in-Place (SIP) protocols. The SS316 body and hygienic seats withstand thermal cycling up to 150°C and aggressive chemical exposure without degradation.
Compact Wafer Profile
Conforms to ISO 5752 Series 19 face-to-face dimensions, allowing easy integration between standard sanitary tri-clamp or industrial flanges without disrupting the hygienic zone of the pipeline.
FDA & USP Class VI Seat Materials
The sealing element is the most critical component for hygiene. We supply single disc wafer check valves exclusively with elastomers and polymers that meet global food and pharma safety standards.
| Seat Material | Compliance Standard | Optimal Application | Temperature Range |
|---|---|---|---|
| FDA EPDM | FDA 21 CFR 177.2600 | Hot water, steam, CIP cleaning solutions, dairy, and beverage lines. Excellent resilience. | -40°C to +120°C |
| USP Class VI Silicone | FDA 21 CFR 177.2600, USP Class VI | High-purity water (WFI, PW), pharmaceutical utility lines, and extreme temperature flexibility. | -60°C to +150°C |
| PTFE (Teflon) | FDA 21 CFR 177.1550, USP Class VI | Aggressive CIP chemicals, solvents, and high-temperature SIP processes. Universal chemical resistance. | -10°C to +180°C |
Engineering Specification Tip
For standard dairy and beverage CIP processes, FDA EPDM is the industry standard due to its excellent steam resistance. For Water for Injection (WFI) loops or highly aggressive chemical cleaning cycles, specify USP Class VI Silicone or PTFE to ensure absolute compliance and longevity.
