There are many types of Japanese standard flanged ball valves. According to the seal, there are hard seals and soft seals. According to the material of the valve body, there are stainless steel, cast steel, cast iron, etc. Today, we mainly introduce the cast iron Japanese standard flanged soft seal ball valves.
The cast iron Japanese standard flange soft sealing ball valve is mainly used to cut off or connect the medium, and can also be used for fluid regulation and control. So, what are its characteristics compared with other valve types?
Features of cast iron Japanese standard flange soft seal ball valve:
1. Small fluid resistance.
2. The switch is fast and convenient. As long as the valve stem rotates 90°, the Japanese standard flanged ball valve completes the fully open or fully closed action, and it is easy to realize rapid opening and closing.
3. Good sealing performance. Cast iron Japanese standard flange soft sealing ball valve seat sealing ring is made of elastic materials such as PTFE, which is easy to ensure the sealing, and the sealing force of the ball valve increases with the increase of medium pressure.
4. Stem seal is reliable. When the Japanese standard flanged ball valve is opened and closed, the valve stem only rotates, so the packing seal of the valve stem is not easy to be damaged, and the sealing force of the valve stem reverse seal increases with the increase of the medium pressure.
5. The opening and closing of the Japanese standard flanged ball valve only rotates 90°, so it is easy to realize automatic control and remote control. It can be equipped with pneumatic devices, electric devices, hydraulic devices, gas-liquid linkage devices or electro-hydraulic linkage devices.
6. The channel of the cast iron Japanese standard flange soft-sealed ball valve is smooth and smooth, and it is not easy to deposit the medium, and the pipeline can be passed through the ball.
