These valves belong to the quarter-turn on/off valve family. This means that a 90-degree turn can either permit or stop the flow of media using a ball-like mechanism inside the valve. Ease of operation is the main advantage of ball valves. In industrial applications, this is a very reliable device for a complete and tight shutoff.
Almost all industrial applications need protection from leaks. This is particularly important to those that require tight shut mechanisms. Such examples are the purely liquid or gaseous applications, including natural gas industries, chemical storage and those that work with corrosive fluids. Slurries don’t work well for these valves.
