Stainless steel flange ball valves are mainly used in places with high requirements for corrosive, pressure, and hygienic environments. Used to cut off or connect the medium in pipelines, different materials are selected and can be applied to various media such as water, steam, oil, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing medium, urea, etc.
Features of stainless steel flange ball valve products:
1. The fluid resistance is small, and its resistance coefficient is equal to that of pipe sections of the same length.
2. Simple structure and small volume.
3. Tight and reliable, currently plastic is widely used as the sealing surface material for ball valves, with good sealing performance.
4. Convenient operation, quick opening and closing, with only 90 ° rotation from full opening to full closing, facilitating remote control.
5. Convenient maintenance, simple ball valve structure, and movable sealing rings, making disassembly and replacement more convenient.
6. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure.
Advantages of stainless steel flange ball valve:
Q41F stainless steel flange ball valve is mainly used to cut off or connect media, and can also be used for fluid regulation and control. Compared to other valve types, ball valves have the following advantages:
1. The fluid resistance is small, and ball valves are one of the valve types with the smallest fluid resistance Z. Even for reduced diameter ball valves, their fluid resistance is relatively small.
2. The switch is fast and convenient. As long as the valve stem rotates 90 °, the ball valve can complete the full open or full close action, making it easy to achieve quick opening and closing.
3. Good sealing performance. The sealing ring of the ball valve seat is generally made of elastic materials such as polytetrafluoroethylene, which is easy to ensure sealing. Moreover, the sealing force of the ball valve increases with the increase of medium pressure.
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 reverse seal increases with the increase of medium pressure.
5. The opening and closing of ball valves only perform 90 ° rotation, making it easy to achieve automated control and remote control. Ball valves can be equipped with pneumatic devices, electric devices, hydraulic devices, gas-liquid linkage devices, or electro-hydraulic linkage devices.
6. The ball valve channel is flat and smooth, and it is not easy to deposit media, making it possible to pass the ball through the pipeline.
