Trunnion Soft Seat Ball Valve

◆ The fixed soft-seal ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque to close tightly. Among them, the ball valve is the most suitable as a shut-off valve. use. It is widely used in pipelines of various working conditions such as petroleum, chemical industry, and thermal power plants. The existence of soft-seal fixed ball valve products can be seen from this, it can be seen that its use is very wide. The main function is to cut off or connect the medium. Applicable media are some corrosive substances like water, steam, oil, nitric acid, acetic acid, urea, etc.

Product structure characteristics

◆ The friction between the ball and the sealing ring is small, and the sealing ring is made of self-lubricating PTFE material, which effectively improves the service life.

◆ Small size, light weight, easy to carry, not so complicated to install, relatively simple to repair and maintain.

◆ The fixed ball valve structure can be installed in any part of the pipeline in any direction.

◆  V-shaped overlapping axial packing, with strong anti-corrosion performance.
