Sanitary Valve Features

Commonly used sanitary valves in food and some wine factories include stop valves, gate valves, ball valves, butterfly valves, plugs, diaphragm valves, plunger valves, pressure reducing valves, safety valves, steam traps, regulating valves, etc. What are their characteristics?

1. Stop valve: The stop valve has a simple structure, convenient maintenance, and has adjustable performance. But its sealing performance is poor and the fluid resistance is large. It is suitable for media such as steam and compressed air, and is not suitable for media with large drilling or containing particles.

2. Gate valve: The gate valve has better sealing performance than the stop valve, small fluid resistance, and has certain adjustable performance. Its disadvantage is that the structure is more complicated and not easy to maintain. It is suitable for water or liquids containing particles and large drilling.

3. Sanitary ball valve: simple structure, small size, light weight; fast switching, easy operation, and small fluid resistance. The disadvantage is that the manufacturing precision requirements are high. It is suitable for high pressure and high caterpillar media; it is not suitable for high temperature and flow regulation.

4. Sanitary Butterfly Valve: simple structure, small size, light weight, fast opening and closing, and has certain adjustable performance. It is suitable for making larger diameters, and is used for liquid or gaseous media with a temperature of less than 80°C and a pressure of less than 1.0MPa. In the food industry, it is often used as a sanitary valve for sanitary pipes of materials because of its simple structure and easy cleaning, which can better meet the hygiene requirements.

5. Plug: It has a simple structure, fast switching, low resistance, and is easy to make into a three-way valve. Its disadvantage is that the sealing surface is easy to wear. It is suitable for fluids with low temperature and pressure, but not for steam or high-temperature media.

6. Diaphragm valve: Its characteristic is that the medium does not enter the inner cavity of the valve cover, and no stuffing box is required. Its structure is also simple, with good sealing and low resistance. It is suitable for media containing suspended matter and acidic media, but not for organic solvents or strong oxidant media.
