1.What is a sanitary valve?
Sanitary valve is a different type from industrial valves, It also called sanitary grade valve or food-grade valve. which is constructed from clean non-toxic stainless steel, designed to controls or regulates the movement of fluid or gas, especially used in food & beverage, dairy, brewing, pharmaceutical, daily chemical, cosmetics industries. Sanitary valve must easy cleaning-in-place (CIP) and circulate CIP fluids.
2.What standard or regulation does a sanitary valve requires?
3-A sanitary standard. The most common standard use in American for valve and fittings is 3-A sanitary standard. Which is specify the criteria for the design and fabrication of equipment that comes into contact with food. The guiding purpose of 3-A Sanitary Standards is to protect public health by using sanitary equipment. Want to know more about 3-A standard, please check this article A Primer for 3-A Sanitary Standards and 3-A Accepted Practices? Donjoy Sanitary valve and fittings are all hygienic design and meet 3-A standard.
FDA standard. The full name is the U.S. Food and Drug Administration(FDA Wikipedia ), which is another standard applied to valve gasket. Donjoy valve seal (e.g EPDM, PTFE, FPM, Silicone, NBR, HNBR) all comply with FDA standard.
ASME BPE standard is related to how to design and manufacture bioprocessing equipment like valve and pipe fittings intended for use in biopharmaceutical and personal-care products industries. Donjoy sanitary valve and pipe fittings as well as meet the standard. For more details please refer to ASME Wikipedia
3.What’s difference between a sanitary valve and an industrial valve?
Material. The sanitary valve body material must use health standards of stainless steel ASI 304 or 316L. But industrial valve body commonly uses carbon steel, alloy steel, cast iron or bronze, which are easily corroded or rust.
Metal surface. The hygienic valve and tube fittings require a high standard of the roughness to the metal surface, all parts that contact with the medium must be finely polished. Surface roughness is calculated measuring the average of surface heights and depths across the surface. This measurement is most commonly shown as “Ra”. SF1 RA20=0.51μm.
The ASME BPE surface finish table as below:
Seal. The seal inside hygienic valve is critical, must meet health standard. Donjoy sanitary valve seal comply with FDA standard.
4. The different application for the sanitary valve and industrial valve.
The sanitary valve application is food processing, water, beverage, brewing, dairy, daily chemical, pharmaceutical industries…
The industrial valve application is oil, gas, slurry, agriculture…
5. What types of sanitary valve have?
6.Valve Connection Type
There are some functional characteristics to end types. Connection end for sanitary valve include:
7.Sanitary Valve Connection Standard and Size: Matching the Pipeline
DIN and 3A, SMS dimension are most commonly used for sanitary pipe connection. Sanitary valve size often means valve port refer to the outside diameter(OD) of pipe.
DIN 11851 DIN standards refer to a series of technical standards originating in Germany. These standards are widely used throughout Europe to ensure norms for quality control, safety, environmental protection and rationalisation. Our sanitary butterfly valve DIN size is from DN10 to DN 300.
3A,SMS dimension in inches. It’s the most widely connection standard used in the world.
The benefit of working with sanitary valve manufacturer in China (Donjoy Technology CO., LTD)
Valves are essential components in various industrial applications, including the processing of oil and gas, water treatment, power generation, and chemical manufacturing. They control the flow of liquids, gases, and other materials through pipelines, ensuring that the process runs smoothly and safely. When it comes to purchasing industrial valves, it’s essential to consider several factors to ensure you’re making the right decision. In this blog post, we’ll guide you through the process of buying industrial valves and help you make an informed purchase.
The first step in buying industrial valves is to determine the type of valve that is appropriate for your application. There are several types of industrial valves, including ball valves, gate valves, globe valves, check valves, and diaphragm valves, among others. Each type of valve is designed to perform specific functions, and choosing the right type will depend on the characteristics of the fluid or material you’re handling, the temperature and pressure of the system, and the level of control you need.
industrial valvesAnother important factor to consider when buying industrial valves is the size and pressure rating. Valves come in different sizes and pressure ratings, and you must choose the appropriate size and pressure rating for your system. The size of the valve is determined by the diameter of the pipeline it will be installed on, and the pressure rating will depend on the maximum pressure the valve can withstand without failing. It’s essential to choose a valve with the correct size and pressure rating to ensure it operates safely and effectively.
When purchasing industrial valves, it’s essential to ensure that they meet relevant certifications and compliance requirements. This will help you avoid purchasing substandard products that may fail prematurely or pose a safety hazard. The most common certifications for industrial valves include API, ISO, and CE. Make sure the valve you choose meets the necessary certifications and standards for your industry and application.
The reputation of the manufacturer is another important factor to consider when buying industrial valves. You want to purchase valves from a reputable manufacturer with a history of producing high-quality products. Look for manufacturers with a solid track record of producing valves that are reliable, safe, and durable. You can research the manufacturer’s history and customer feedback to get a better understanding of its reputation.
The cost of industrial valves is another important factor to consider, and it’s essential to find a balance between price and quality. While it may be tempting to opt for the cheapest option, this may not always be the best decision in the long run. High-quality valves can be more expensive, but they are typically more reliable and will last longer, saving you money in the long run.
In conclusion, when buying industrial valves, it’s essential to consider several factors to ensure you’re making an informed decision. From determining the type of valve you need, to evaluating the manufacturer and considering the cost, these are all crucial factors that will impact the success of your industrial application. By taking the time to consider these factors, you can be confident that you’re making the right decision and purchasing industrial valves that will meet your needs and provide long-lasting performance.
