Principle: When fully opened, the unimpeded valves on both sides form a straight pipe channel and are sealed in both directions. The pneumatic O-ring ball valve has better self-cleaning performance, and is suitable for two position cutting occasions that are especially dirty and contain fiber media. The ball core always rubs with the valve during the opening and closing process of the valve. At the same time, the sealing between the valve core and the valve seat is achieved by the pre tight sealing force of the valve seat against the ball core. However, due to the excellent mechanical and physical properties of the soft seal valve seat, its sealing performance is particularly good.

First of all, this pneumatic ball valve has strong environmental adaptability, which means that it can operate in both high and low temperatures, while ordinary products of the same type can not continue to work in high or low temperatures. However, the pneumatic ball valve solves this problem, and it can operate well in any working environment, Therefore, it has great competitiveness among similar products.
