Hygienic Wafer Type NRV and Pharma Check Valve Features
When choosing a check valve for the pharmaceutical industry, having a hygienic design is essential. Our hygienic wafer NRV (Non-Return Valve) is made with smooth internal surfaces and no crevices to stop bacteria from building up. That makes it the best choice for food grade non return valves used in dairy, beverage, and pharmaceutical systems.
Stainless Steel 304 (CF8) is the standard material used in general food processing and pharmacy setups. It offers a good balance of resistance to corrosion, strength, and cost, and can handle regular exposure to water, steam, mild cleaners, and organic acids.
Crevice-Free Construction
Smooth inside parts and carefully made components stop dead spots where bacteria or product could build up.
CIP & SIP Compatible
These valves can handle the heat and chemicals used in Clean-in-Place (CIP) and Sterilize-in-Place (SIP) processes.
Smooth Surface Finish
Standard polished surfaces (Ra < 1.6 µm) stop microbes from sticking. Electropolished finishes are available if needed.
Compact Wafer Profile
The ISO 5752 Series 19 face-to-face measurements allow for easy installation between regular sanitary or industrial flanges.
CF8 Single Plate Check Valve Technical Specifications
As a strong CF8 Single plate check valve, this product allows for fast, complete closure to stop water hammer. The spring-loaded Single plates stop any backflow, and the wafer design follows international standards to make retrofitting easier.

Frequently Asked Questions (FAQ)
Q1: Are your SS304 wafer check valves suitable for food and pharma uses?
Yes. Our SS304 (CF8) wafer check valves are built for hygienic environments. They have smooth internal surfaces, no crevices, and come with FDA-compliant and USP Class VI certified seat materials (EPDM, Silicone, PTFE) that work well with Clean-in-Place (CIP) and Sterilize-in-Place (SIP) processes.
Q2: What is the difference between SS304 and SS316L for pharma valves?
SS304 (CF8) is great for general food processing, beverage, and pharma utility lines (like cooling water, compressed air, and non-chloride DM water). For more strict GMP lines, highly chlorinated water, or harsh cleaning solutions, we recommend SS316L (CF3M) as it offers better protection against pitting corrosion.
Q3: Do you provide material and hygiene certificates?
Yes. Each batch includes a Material Test Certificate (MTC) as per EN 10204 3.1. We also provide FDA compliance statements for the elastomers, USP Class VI certificates on request, and ISO 9001:2015 certification for our manufacturing.
Q4: What sizes and pressure ratings do you offer?
We offer SS304 wafer Single plate check valves from DN50 (2 inch) up to DN600 (24 inch). The standard pressure ratings are PN10, PN16, and Class 150. They meet API 594 and ISO 5752 Series 19 face-to-face dimensions for easy fitting between standard flanges.
Q5: What is the MOQ and delivery time for pharma-grade valves?
The minimum order quantity is 10 units per size and configuration. Standard SS304 sizes (DN50–DN200) with EPDM or PTFE seats usually ship within 7–10 working days. Custom polished finishes or specific elastomer certifications may take 10–15 working days. Delivery across India takes 2–5 working days.
