Butterfly valves for powders and granules
Ensure precise flow control and reliable sealing for gravity-fed or pneumatic systems with these versatile butterfly valves designed for efficient interception of powders and granules in various manufacturing processes.
Intercepts and Seals Powder and Granular Flow
The Butterfly Valves VFS from WAMGROUP are engineered to provide precise control in the interception and sealing of powdery and granular materials. These valves stand out due to their robust construction, featuring high-pressure aluminum alloy die-cast semi-bodies and an interchangeable disc in either SINT engineering polymer or stainless steel, making them highly abrasion-resistant. Designed for diverse applications in industries such as construction, food processing, and chemicals, they efficiently handle materials from bulk solids to pharmaceuticals.
Their unique design allows seamless integration below hoppers, silos, and conveyors, ensuring dust-tight and pressure-proof operation up to 0.2 bar. VFS valves are available in multiple configurations, including food-grade versions compliant with FDA and EN standards, to meet specific industry requirements. With options for ATEX certification, the VFS valves are suitable for use in potentially explosive atmospheres.
Operating through gravity-fed or pneumatically conveyed materials, they manage flow with minimal components, ensuring easy fitting and low maintenance, while ex-stock delivery enhances availability. The VFS valves facilitate both manual and continuous operations, optimizing process efficiency across various sectors.
