Pneumatic floating ball valve is used to cut off or connect the medium in pipeline. It is applicable for water, steam, oil, gas, acetic acid, nitric acid, urea, etc.
Advantages
1. Compared with other valves, pneumatic floating ball valve has the least fluid resistance. When the valve opened completely, channel in valve and pipes form a straight way so that medium can pass through without any loss.
2. Compared with gate valve and globe valve having the same dimensions, ball valve has small volume and light weight.
