There are different types of sanitary valves available in the market. These valves vary based on the purpose and make of each one. These are the most popular types of sanitary valves.
PVC coated pipe is a popular choice for sanitary valves in the dairy industry. It can resist food-borne diseases such as Salmonella. It is also able to prevent oil and grease from mixing with milk, preventing the possibility of contaminated oil and water mix which can lead to bacterial contamination.
PVC coated pipe is able to maintain its pliable form during years of wear and tear and is resistant to corrosion. It can meet industry requirements such as controlling flow rate, maintaining line tension, preventing backflow of contaminated liquids, and preventing backflow spillage. It is used extensively in laboratories, food processing plants, and industrial production lines. Its availability in a variety of sizes and configurations makes it suitable for any size of operation.
The butterfly valve is another option, which is very similar to the PVC-coated pipe. However, the key difference is that the butterfly valve does not require a plumber's permission to be installed, unlike the PVC coated pipe. The only restriction to using these sanitary valves is the design of the hole in which they are installed. The most commonly used types are the round-shaped and the straight-end butterfly valves.
For leak detection and prevention, industries require high-quality sanitary valves, which can withstand extreme temperatures and pressures. There are many materials that can be used to make industrial valves, including brass, stainless, titanium, iron, and Teflon coated steel. These materials vary in the level of resistance to different conditions and elements, which ultimately determines the maintenance and operating costs. There are also differences in the longevity of materials, which is important when it comes to industrial lubricants or coatings.
All the sanitary valves need are basic elements, such as the seat area, seat bottom area and valve seat. The seat is where the valve will be installed. The bottom is where leaks will occur. Manufacturers recommend using a combination of materials to construct these valves. However, there are other options. Some companies prefer stainless steel for its durability. However, the choice largely depends on the type of industry, grease management techniques, operating environment and other factors.
Apart from selecting the correct materials and the correct specifications, the thickness of the seat and the valve seat is one of the most critical components. For example, in the dairy industry, the performance and function of the device is directly affected by the thickness of its seat or the depth within the cavity. Many people think that these two elements are generally the same, but they are not. To ensure leak-free operations, the dairy industry requires crevice-free valves that are more durable and longer-lasting.
Crevice-free valve bodies are ideal for food processing plants. These sanitary valves can have solid or semi-solid bodies with the ball's inner surface being completely smooth. As the valve body is smooth, this eliminates all chances of spillages, which are quite common in the food-processing and food-related industries. Butterfly sanitary valves are also used in food-related industries. Butterfly ball valves have tapered bodies and tapered seat bottoms, which prevent the entrance of airborne particles. Apart from being highly functional, butterfly valve bodies are also highly appealing in terms of looks and style, which make them popular among many industrial users and for home consumption as well.
