Q41F stainless steel ball valve
Product Introduction:
Q41F-16RLStainless steel 316L ball valve CF3MStainless steel flange ball valve Q41F stainless steel ball valve/Q341F worm gear stainless steel ball valve/manual stainless steel ball valve/handle stainless steel ball valve/acid alkali resistant stainless steel ball valve/Q941F electric stainless steel ball valve/Q641F pneumatic stainless steel ball valve/stainless steel switch cut-off ball valveMainly used in places with high requirements for corrosiveness, pressure, and hygiene environment. Suitable for various pipelines ranging from Class 150 to Class 1500, PN16 to PN63, and JIS10K to JIS20K, it is used to cut off or connect media in pipelines. Different materials are selected and can be applied to various media such as water, steam, oil products, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing media, urea, etc.

Product Features:
1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment 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, which has good sealing performance.
4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.
5. Easy to maintain, the ball valve structure is simple, and the sealing rings are generally movable, making disassembly and replacement relatively convenient.
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 used from high vacuum to high pressure.

Advantages:
Q41F stainless steel flange ball valve is mainly used for cutting off or connecting media, and can also be used for fluid regulation and control. Compared with other types of valves, ball valves have the following advantages:
1. Low fluid resistance, ball valve is one of the valve types with the lowest fluid resistance Z, even for reduced diameter ball valves, its fluid resistance is quite small.
2. The switch is fast and convenient. As long as the valve stem rotates 90 °, the ball valve completes the fully open or fully closed action, making it easy to achieve rapid 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, and 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 the ball valve can only rotate 90 degrees, making it easy to achieve automation and remote control. The ball valve can be equipped with pneumatic, electric, hydraulic, pneumatic hydraulic or electro-hydraulic linkage devices.
6. The ball valve channel is flat and smooth, not easy to deposit media, and can be used for pipeline ball passing.
