Q347PPL-900LB soft-sealed forged steel ball valve features:
The soft-sealed forged steel ball valve has compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are always in a closed state, which is not easy to be eroded by the medium. It is easy to operate and maintain. It is suitable for general working media such as water, solvent, acid and natural gas. It is also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., and is widely used in various industries. The ball valve body can be integral or combined.
Advantages of Q347PPL-900LB soft-seal forged steel ball valve:
1. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.
2. Simple structure, small size and light weight.
3. Close and reliable. It has two sealing surfaces, and the current sealing surface materials of ball valves are widely used in various plastics, which have good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.
4. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.
5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.
7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.
8. Since the ball valve has wiping properties during opening and closing, it can be used in media with suspended solid particles.
