A valve is a device that regulates, directs, or controls the flow of a fluid (gas, liquid, fluidized solids, or sludge) by opening, closing, or partially obstructing various passages.
The valve body should meet the hygienic standard of stainless steel and all contact parts with the the medium should be mirror polished, polishing and cleaning are subject to hygienic standards for valve assemblies. Sanitary valve is mostly used in clean areas of food processing, pharmaceuticals, & hospitals, also places with high requirements for hygienic grades & no physical or chemical hazards.
Sanitary valves has its own need for their body materials and sealing material. Sanitary valves are stainless steel and their seat covers should be non-toxic, such as rigid stainless steel gaskets and soft rubber gaskets.
The contact parts between sanitary valves and fluids are mainly stainless steel, the material is usually 304SS or 316 SS, which is a non-toxic and harmless material with a clean and smooth surface that will not cause corrosion and chipping. Sanitary valves are in many ways beyond the reach of industrial 6400 hygienic ball valve with 2 position manual lever, such as cleanliness, installation methods, etc., so they are specialized valves for food, medicine, & other industries.
Advantages of Sanitary Valve
- Crevice free– The applications of the sanitary valves in the industry such as food and the doctor denounces the fact that these must be free from any form of contamination. And if there is a crack in the valves, there are more chances of the same. Therefore, the valve manufacturers make sure that there is no more space for the space, in order to avoid any kind of contamination. Without the crack, there will be no problems related to the hygiene of the plant in particular.
- Easy to clean– Food and Dairy Industry are the two industries which has to maintainin the maximum hygiene. There will still be a lot of work to be done in industries, such as regulation the flow of the product, ensuring the right amount of components, maintaining the temperature. Therefore, the cleaning work mustn’t be cumbersome. Sanitary valves are easy to clean because they do not get stained easily.
- The surface of the valves–To prevent it from rust and corrosion, you’ll have to keep the surface smooth and polished. The amount of expense required to replace valves that rust and degrade pipes is simply too high. To avoid them, sanitary valves are available, in polished stainless steel.
Industrial valves are made to withstand the conditions, many of which are used in high temperature and high pressure working environments. Industrial valves have a long service life and flexible operation modes and are widely used in machinery, metallurgy, petrochemical, chemical, urban construction, and other industries.
