An Insight on Sanitary Valves and Its Various Applications
Sanitary valves are used in various applications requiring sterile or clean processing. A valve is considered sanitary when it is free from cavities or crevices so that there is not trap for the bacteria to feed and multiply. There is a need to polish the wetted surfaces and the radius is bought to a minimum size so that the media entrapped or clinging is avoided. The brass, plastic, and other materials are used in stainless steel as sanitary applications and it is highly preferred. The sanitary valves common applications are:
- Food & Beverage
- Wine & Spirits, Brewing
- Fragrance and cosmetics
- Sterilizing Equipment
The sanitary valves are in many types. They are used widely in food and drinks industries. the main reason is the steel parts that are acid-proof and the sealing parts are in polytetrafluoroethylene material or food silicone rubber, confirming to the standards of food hygiene. To name a few are:
Ball Valves – These are extensively used in dairy products, food, wine, beverages, pharmaceutical, fine chemicals, and biological engineering.
Butterfly Valves – These butterfly valves are also in stainless steel. It is also essential for the food and beverage industries so that it maintains the security of food and water.
Diaphragm Valves – These types of sanitary valves are used widely in dairy and food products and also in other industries. To meet the demands that is increasing to shrink the valve overall envelope assemblies has resulted in the valve manufacturers to develop this sanitary diaphragm as a block body.
Shutoff and Diverter Valves – These are the types of valves when closed allows the fluid to pass through the tube and there is no dead leg virtually between the weir and the tube.
Regulating Valves – These types of valves are the assembly types used typically for simple process such as sampling and diversion.
Sample Valves and Gauges – These are widely used in biological and pharmaceutical engineering industries.
Constant Pressure Valves – This is the most common valve types that are used in the sterile access and in the assembly of GMP valve type.
Air/Pressure Relief Valves – This type of valves feature commonly the main valve mounted horizontal, though the GMP valve main valve is vertically mounted.
Tank Bottom Valves – These are the valves that are the diaphragm type and its design allows the valve designers to machine multiple valves into a stainless steel block.
