Fit-frame butterfly valves for dry bulk solids
In bulk solids processing, ensuring optimal material flow and reducing contamination is crucial, especially when dealing with food or sensitive materials. Challenges often include residue buildup and ensuring compliance with food safety standards.

Control flow and reduce contamination
The Fit-Frame Butterfly Valves VFP/VFPX by WAMGROUP provide an innovative solution for controlling the flow of dry bulk solids. These valves are designed to minimize material residue between the valve and the connected feeding device, which significantly reduces contamination risks. They are compliant with Regulation (EC) No. 1935/2004, making them suitable for food-related applications. The valves consist of high-pressure die-cast semi-bodies made of aluminum alloy and a swivel disc that can be constructed from cast iron, stainless steel, or engineering polymers like SINT. The pre-stressed elastomeric seal and optional FDA-approved seal for food applications enhance functionality. Ideal for installation beneath hoppers, bins, silos, or conveyors, these valves excel in environments requiring frequent material flow interception. They support easy maintenance with a minimal number of components and are lightweight due to their compact design.
