It has further improved the domestic productivity and sales volume, and introduced domestic industrial equipment abroad, which has huge development potential. It also has a good role in promoting the development of other types of pneumatic ball valves. In addition to the overall product, China has also designed the production and use of relevant parts, such as pressure reducing valves, The throttle valve and other parts are necessary for equipment production, which also promotes the development of this industry to the future market.

Therefore, appropriate materials should be selected correctly to extend the service life of the valve. In addition, the influence of high temperature aging on the physical functions of materials, such as the modification of resistance and intergranular corrosion, should also be considered. When the application temperature reaches or exceeds the heat treatment temperature, the valve internals will undergo annealing and the hardness will decrease by one level. In order to prevent the material hardness from changing, the selection of the maximum temperature limit must be within a safe range.
