Butterfly valves are valves that can be used to isolate or regulate flow. The shutdown mechanism takes the form of a disk. Operates like a ball valve and closes quickly. Butterfly valves are generally preferred because they cost less than other valve designs and are lighter, which means less support is required. The disc is in the center of the pipe, and a rod that goes through the disc is connected to the actuator on the outside of the valve. Rotating the actuator can make the disc parallel or perpendicular to the flow. Unlike ball valves, the disc is always present in the flow and therefore always causes a pressure drop in the flow regardless of valve position.

  • Lightweight and easy to handle

  • To close silos, hoppers or waste bins filled with powder or granules, the VFS butterfly valve is one of the most widely used equipment worldwide.
  • What used to be a custom project for a specific application, VFS has been transformed into an industrially produced industrial product with a lot of functionality.
  • VFS butterfly valves are used in all types of powder and granular material processing plants that need to intercept dry materials conveyed by gravity or pneumatically. They are installed under hoppers, bins, silos, screw or other types of conveyors, or intercept pneumatic conveying pipes. They represent a particularly cost-effective solution due to the use of special design and engineering materials.
