Butterfly valves for dry powder and granule flow interception
Ensure precise control over material flow in your processing line with these robust butterfly valves, designed for efficient handling of dry powders and granules.

Intercepts and Controls Bulk Solids Flow
The VW Butterfly Valves from WAMGROUP are engineered for precise material interception in bulk solids handling scenarios across diverse industries such as building materials, food, and heavy industries. These valves, crafted from robust die-cast aluminum with a choice of carbon or stainless steel discs, ensure durability and compatibility with aggressive materials. Specially designed for both pneumatic and gravity-fed systems, they efficiently handle powders and granules with operating pressures up to 2.5 bar. With interchangeable discs and a replaceable elastomer seal, the valves promise easy maintenance and minimal downtime. Their adaptability to manual, pneumatic, or electric actuation facilitates seamless integration into automated production lines. Available in sizes complying with DIN and ISO standards, they cater to a variety of specific industrial needs, ensuring smooth operation in processing facilities producing cement, various glass products, and metallurgical outputs.
