Why SS304 for Pharma & Food Processing?
Stainless Steel 304 (CF8) is the industry-standard material for general food processing, beverage production, dairy, and pharmaceutical utility systems. It offers an optimal balance of corrosion resistance, mechanical strength, and cost-effectiveness. SS304 withstands routine exposure to water, steam, mild cleaning agents, and organic acids commonly found in these environments.
While SS316L is recommended for highly chlorinated or aggressive GMP process lines, SS304 remains the most specified and economical choice for compressed air, cooling water, non-chloride DM water, and general utility piping where strict hygiene and easy cleanability are paramount.
Hygienic Design Features
In pharma and food applications, valve design is as critical as material selection. Our SS304 wafer check valves are engineered to meet stringent hygiene standards:
Crevice-Free Construction
Smooth internal contours and precision-machined components eliminate dead legs and crevices where bacteria or product residue could accumulate.
CIP & SIP Compatible
Designed to withstand the thermal cycling and chemical exposure of Clean-in-Place (CIP) and Sterilize-in-Place (SIP) protocols without seat degradation.
Smooth Surface Finish
Standard polished internal surfaces (Ra < 1.6 µm) prevent microbial adhesion. Electropolished (Ra < 0.8 µm) finishes available on request for strict GMP lines.
Compact Wafer Profile
ISO 5752 Series 19 face-to-face dimensions allow installation between standard sanitary or industrial flanges without disrupting pipeline hygiene zones.
FDA-Compliant Seat Materials
The sealing element is the most critical component for hygiene. We supply wafer check valves with elastomers and polymers that meet global food and pharma safety standards:
| Seat Material | Compliance | Best Suited For | Temperature Range |
|---|---|---|---|
| FDA EPDM | FDA 21 CFR 177.2600, USP Class VI | Hot water, steam, CIP cleaning solutions, dairy, and beverage lines. Excellent resilience and compression set. | -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 applications requiring 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 processes where elastomers may degrade. Universal chemical resistance. | -10°C to +180°C |

Frequently Asked Questions
1. Are your SS304 wafer check valves suitable for food and pharma applications?
Yes. Our SS304 (CF8) wafer check valves are specifically designed for hygienic applications. They feature smooth internal surfaces, crevice-free design, and are available with FDA-compliant and USP Class VI certified seat materials (EPDM, Silicone, PTFE) suitable for Clean-in-Place (CIP) and Sterilize-in-Place (SIP) processes.
2. What is the difference between SS304 and SS316L for pharma valves?
SS304 (CF8) is highly suitable for general food processing, beverage, and pharma utility lines (cooling water, compressed air, non-chloride DM water). For strict GMP process lines, highly chlorinated water, or aggressive cleaning agents, we recommend upgrading to SS316L (CF3M) for superior pitting corrosion resistance.
3. Do you provide material and hygiene certificates?
Absolutely. Every batch is supplied with a Material Test Certificate (MTC) as per EN 10204 3.1. We also provide FDA compliance declarations for elastomers, USP Class VI certificates on request, and ISO 9001:2015 quality management certification for our manufacturing processes.
4. What sizes and pressure ratings are available?
We supply SS304 wafer dual plate check valves from DN50 (2 inch) to DN600 (24 inch). Standard pressure ratings are PN10, PN16, and Class 150, conforming to API 594 and ISO 5752 Series 19 face-to-face dimensions for easy retrofitting between standard flanges.
5. What is the MOQ and delivery time for pharma-grade valves?
The Minimum Order Quantity (MOQ) is 10 Nos per size per configuration. Standard SS304 sizes (DN50–DN200) with EPDM or PTFE seats typically dispatch within 7–10 working days. Custom polished finishes or specific elastomer certifications may require 10–15 working days. Pan India transit takes 2–5 working days.
