VFS Butterfly Valves

VFS Butterfly Valves

VFS butterfly valves are invaluable parts in many types of industrial equipment used in various powder and granular material processing facilities. A common installation spot is underneath bins, hoppers, silos and conveyors, where they perform the crucial role of assisting in the interception of pneumatically conveyed or gravity-fed materials. 

Deca Vibrator Industries, Inc. offers high-quality VFS butterfly valves for various applications. We specialize in producing customizable bulk material handling and vibration equipment for numerous industries. 

VFS Butterfly Valve Features and Options

Our extensive butterfly valve selection consists of multiple single- and double-flange versions. Available disc types include cast iron or SINT® polymer composite, and you can choose from manual, electric and pneumatic actuators. Both V1FS and V2FS models start in a 4-inch size and increase in 2-inch increments up to 16 inches. 

Numerous options are available to enhance the valve’s functionality and performance. Examples include manual lever straight and bent handles, pneumatic drives, position limit switches, and spring return and double-inching solenoids.  

Innovative Features

  • V1FS with top flange and beaded bottom section suitable for fixing a flexible sleeve
  • V2FS with identical top and bottom flange
  • Dust tight and pressure-proof up to 0.2 bar (2.9 PSI)
  • High-pressure, aluminum alloy die-cast semi-bodies
  • Disc in cast iron, SINT engineering polymer, or stainless steel
  • Seals for standard or food-grade applications
  • Made up of few components
  • Used for powders, granules, pellets
  • Lightweight and easy to handle

What Are the Benefits of a VFS Butterfly Valve?

The many benefits of our VFS butterfly valves include:

  • Solid construction: These valves consist of an aluminum alloy for superior strength and a pre-stressed elastomer seal for exceptional performance.
  • Versatility: You can use these interchangeable valves for a wide range of applications in multiple industries. 
  • Abrasion resistance: They can withstand the wear and tear of friction from frequent scraping and rubbing.
  • Easy installation: You can install these valves quickly, easily and securely. 
  • Simplified maintenance: You won’t waste valuable time and labor servicing your valves.

Typical Applications

VFS butterfly valves deliver exceptional results while performing various functions for companies in numerous industries:

  • Grain storage and handling
  • Flour, rice and animal feed processing
  • Chemical 
  • Plastics and rubber processing
  • Dry mix building materials processing
  • Fire protection
  • Dry detergent, soap and cosmetics processing
  • Sanitary fittings
  • Fly-ash handling in power plants
  • Concrete production

Examples of industry-specific functions performed by VFS butterfly valves include contributing to quality, safety and cleanliness in the dry and bulk food processing industry. The adjustability enables workers to control the flow of media and ingredients, making it easier to streamline operations and increase efficiency. 

In concrete batching plants, they’re fitted underneath hoppers, silos and bins to act as shut-off valves to assist in the interception of cement and other dry or powdery gravity-fed or pneumatically fed materials. Their high level of durability and reliability allows them to handle these aggressive media.  

These devices can also serve as shut-off valves in bulk processing and other industrial applications. Examples include asphalt mixing, dry mix processing and lime dosing. The multiple sizes and designs enable their use at varying pressures.

Available Options

  • ATEX –certified
  • Compliant with EN 1935/2004 standards
  • Food-grade version with stainless steel disc and integral seal
