Sanitary ball valve is a straight through ball valve, sealed by spherical surface, so it can be used in both vacuum and low pressure conditions, and can be installed at any position. Sanitary ball valve is suitable for connecting or cutting off medium flow in vacuum system. So do you know the structural characteristics and classification of sanitary ball valve?

The structural features of sanitary quick fit ball valve are as follows:

1. The flow resistance is small, and its resistance coefficient is equal to that of the same length of pipe.

2. It has the advantages of simple structure, small volume and light weight.

3. At present, the sealing surface material of ball valve is widely used in plastic with good sealing performance, and it has been widely used in vacuum system.

4. It is easy to operate and quick to open and close. Only 90 ° rotation is needed from full opening to full closing, which is convenient for remote control.

5. When the valve is fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, which will not cause erosion of the valve sealing surface when the medium passes through.

6. Maintenance is convenient, ball valve structure is simple, seal ring is generally movable, disassembly and replacement are more convenient.

Sanitary ball valves are classified as follows:

1. According to the connection mode, it can be divided into screw plug and flange plug.

2. According to the sealing mode, it can be divided into tight set plug valve, packing sanitary ball valve, self sealing sanitary ball valve, oil lubricated sanitary ball valve, soft seal sanitary ball valve, etc.

3. According to the structural form, it can be divided into cylindrical plug valve, conical plug valve, three-way sanitary ball valve, angle sanitary ball valve, high-temperature plug valve and fire-proof sanitary ball valve.

The working medium of sanitary ball valve is acid and alkaline gas or liquid. It is used in dairy products, wine industry, bioengineering, food, pharmacy, beverage, cosmetics and chemical industry.
