Butterfly valves for powder and granular material handling

Experience seamless material control with advanced butterfly valves, designed to efficiently intercept and discharge powders and granules in continuous and manual operations, ensuring consistent flow and optimal process integration.

Controls and Intercepts Material Flow

The Butterfly Valves VFS from WAMGROUP offer reliable interception and discharge solutions for powdery and granular materials in various industries. These valves are constructed with high-pressure aluminum alloy die-cast semi-bodies and feature a SINT polymer composite or stainless-steel disc, ensuring durability and corrosion resistance. They are essential for processes requiring material flow control, such as construction, feed, food, plastics, and chemicals industries. The VFS valves handle the interception of gravity-fed or pneumatically conveyed materials effortlessly, accommodating a range of operations from continuous to high-speed. Designed for integration, they fit beneath hoppers, bins, silos, and conveyors, and are compatible with upstream and downstream processes in your production line. Additionally, their dust-tight and pressure-proof design up to 0.2 bar ensures operational efficiency and safety. Enjoy low maintenance costs and easy disc interchangeability, with options for food-grade applications to meet industry standards.

Benefits

  • Enhances material processing efficiency with precise flow control.
  • Minimizes maintenance downtime with easy-to-replace components.
  • Provides seamless integration with existing hoppers, bins, and conveyors.
  • Reduces operational costs due to durable, abrasion-resistant design.
