Slide valves for flow interception in powder and granular materials
Managing the flow of powdery or granular materials in gravity or conveying applications can be challenging. Ensuring efficient material handling while maintaining durability and ease of maintenance is essential, particularly in industries like food processing and wastewater treatment.

Intercept and control material flow with precision
The VL Slide Valves from WAMGROUP are designed to intercept the flow of powdery or granular materials in gravity or conveying applications. The valves feature a two-piece carbon or stainless steel frame coated with WAM’s SINT engineering polymer composite, and a sliding blade available in SINT engineering polymer, carbon steel, or stainless steel. This design significantly increases abrasion resistance compared to traditional valves and eliminates the need for flange gaskets. Several configurations are available, including rectangular, square, and circular cross-sections, as well as an option with an integrated pneumatic actuator. These valves are suitable for installation on hopper or silo outlets, conveyor inlets and outlets, and inlet telescopic loading spouts. The special geometry and blade design enable their use across various industries, including food processing. Additionally, the compact dimensions of the VLS version make it ideal for conveyor outlets. The valves are covered by a patent, ensuring innovative and reliable operation.
