As the name implies, a sanitary valve is a type of valve that meets specific health and safety standards for food, beverage, medical, and other applications. The purity of the consumable products that flow through sanitary valves is dependent on their sterility. The valve body is typically made of stainless steel, which meets stringent health standards. Mirror polishing is used on all parts that come into contact with the fluid, gas, or slurry medium. The level of polishing and cleanliness must meet the health standards required by the industrial function.
It is most commonly found in the sanitary areas of food processing plants, pharmaceutical plants, and hospitals. It’s also used in environments with stringent health regulations that mandate a zero-tolerance policy for physical and chemical hazards. To meet certain health standards, all sanitary valves must be disinfected. Non-sanitary valve manufacturers are unable to produce such valves because all toxic components (such as lead) must be removed, which can cause poisoning, cancer, or even death. As a result, most sanitary valves are made entirely of stainless steel.
Another significant element of sanitary valves is the absence of crevices, cavities, and sharp corners where bacteria and other foreign matter can accumulate. They must also be suitable with simple cleaning-in-place (CIP) procedures.
Types of Sanitary Grade
Sanitary valves could be built in numerous different ways, and they are divided into three categories depending on their mechanical motions. Linear motion, rotary motion, and quarter-turn valves are the three distinct classes.
- Linear Motion Valves: – These valves use a closing member and move in a straight line to allow, stop, or throttle medium flow. Linear motion valves include gate, globe, diaphragm, pinch, and lift check valves.
- Rotary Motion Valves: – A valve-closure member that moves across an angled or cylindrical path is used. Butterfly, ball, plug, eccentric, and swing check valves are some of the most common types of rotary motion valves.
- Quarter Turn Valves: – They are essentially rotary motion valves that require only a quarter-turn (or 0 through 90°) stem motion to move from fully open to fully closed or vice versa.
- Sanitary Valves: – They are widely used in industries and at home because they demonstrate their benefits. Because of their numerous advantages, these valves should be widely used. Here are some of the advantages of using sanitary valves.
- Crevice free: – The applications of sanitary valves in industries such as food and medicine demonstrate the need for these to be free of contamination. And if there is a crevice in the valves, the chances of this happening increase. As a result, the valve’s designers make certain that there is no room for the crevice to avoid contamination. There will be no problem with the plant’s hygiene if the crevice is not present.
- Easy to clean: – The food and dairy industries are the ones where hygiene and health are of the utmost importance. In any case, there will be a lot of work involved in the industries, such as regulating the flow of the product, ensuring the right amount of components, and maintaining the temperature. As a result, the cleaning work must be as simple as possible. Sanitary valves are simple to clean because they do not stain easily. As a result, it is simple to use.
The Surface of the Valves
If the surface of the valves is smooth and polished, it does not rust or corrodes. The amount of money wasted in changing the valves that rust and degrade the pipes is far too high. Sanitary valves made of polished stainless steel are available to avoid these problems.
