Butterfly and ball valves

The butterfly valves are shut-off valves relatively simple, with a large passage section and they offer a poor resistance to flow. These features place the butterfly valves at base of modern technology for process systems and they make them ideal for use with medium and high viscosity products. The ball valves are designed to offer a full-flow section advantage. In this way the product crosses valve without any shrinkage, reducing to a minimum the pressure losses.
