Hygienic ball valve product introduction description

The sanitary ball valve is evolved from the cock. Its opening and closing member acts as a sphere, which is opened and closed by rotating the ball 90o around the axis of the valve stem. The ball valve is mainly used to cut, distribute and change the flow direction of the medium on the pipeline. The ball valve designed as a V-shaped opening also has a good flow regulation function. The ball valve not only has a simple structure and good sealing performance, but also has a small volume, light weight, low material consumption, small installation size, small driving torque, simple operation and easy opening and closing in a certain nominal passage range.
 
Hygienic ball valves are one of the fastest growing valve varieties in the last decade. Especially in the developed countries of the United States, Japan, Germany, France, Italy, West, Britain and other industries, the use of ball valves is very extensive, the variety and quantity of use continue to expand, and to high temperature, high pressure, large mouth, high sealing, long The life, excellent adjustment performance and the development of a multi-valve direction have achieved a high level of reliability and other performance indicators, and have partially replaced gate valves, globe valves, and throttle valves. With the technological advancement of ball valves, there will be wider applications in the foreseeable short-term, especially on oil and gas pipelines, on refinery crackers and in the nuclear industry. In addition, in the large and medium-sized, medium and low pressure areas of other industries, ball valves will also become one of the leading valve types.
 
Ball valves are a kind of valve that came out in the 1950s. For half a century, ball valves have developed into a major valve category. The ball valve is mainly used to cut off or turn on the medium, and can also be used for fluid regulation and control. The V-type ball valve can perform more precise flow regulation and control, while the three-way ball valve is used to distribute the medium and change the flow direction of the medium.
 Hygienic ball valves have the following advantages:

 1. The fluid resistance is small. The ball valve is the one with the least fluid resistance in all valves. Even for the reduced diameter ball valve, the fluid resistance is quite small.

 2, the switch is quick and convenient, as long as the valve stem rotates 90°, the ball valve completes the full opening or full closing action, and it is easy to achieve quick opening and closing.
3. Good sealing performance. The ball valve seat sealing ring is generally made of an elastic material such as Teflon, which is easy to ensure the sealing, and the sealing force of the ball valve increases as the medium pressure increases.
4. The valve stem seal is reliable. When the ball valve is opened and closed, the valve stem only rotates, so the packing seal of the valve stem is not easily damaged, and the sealing force of the valve stem inverted seal increases with the increase of the medium pressure.
5. The opening and closing of the ball valve only makes 90° rotation, so it is easy to realize automatic control and remote control. The ball valve can be equipped with pneumatic device, electric device, hydraulic device, gas-liquid linkage device or electro-hydraulic linkage device.
