Structural features of imported forged steel ball valve:
1. The resistance coefficient of the fluid is equal to that of the same length of pipe segment.
2. Simple structure, small volume and light weight.
3. It is compact and reliable. Now, the sealing surface material of ball valve is widely used in plastic, with good sealing performance. It has also been widely used in vacuum system.
4. It is easy to operate and fast to open and close. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.
5. Maintenance is convenient, ball valve structure is simple, sealing ring is generally movable, disassembly and replacement are more convenient.
6. When the valve is fully open or closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes through, the valve sealing surface will not be eroded.
7. It has a wide range of applications, ranging from small diameter to several millimeters and large diameter to several meters, from high vacuum to high pressure. When the ball rotates 90 degrees, it should be spherical at the inlet and outlet, so as to cut off the flow.
