Advantages of pneumatic stop valve

1. The action is reliable, and the stem axis of the stop valve is perpendicular to the sealing surface of the valve seat. The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off action.

2. There is no friction when opening and closing, the sealing surface is not easy to wear and scratch, and the sealing performance is good. When opening and closing, there is no relative sliding between the valve disc and the sealing surface of the valve body, so the wear and scratch are not serious, the sealing performance is good, and the service life is long.

3. Top mounted structure. The valve installed on the pipeline can be directly inspected and maintained online, which can effectively reduce the shutdown of the device and reduce the cost.
