Vacuum butterfly valves can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favoured because they are lighter in weight, meaning less support is required. These low vacuum butterfly valves have a high purity polished surface and user friendly design.
