Flap diverter valves for pneumatic conveying

Streamline material flow in your pneumatic conveying system by effortlessly redirecting powders, pellets, or granules, ensuring minimal pressure drop and high sealing efficiency in your production process.

Diverts and Routes Powders, Pellets, and Granules

The VAB Flap Diverter Valve from WAMGROUP is designed for effective rerouting in pneumatic conveying systems, diverting powders, pellets, and granules with precision. Its swinging flap mechanism ensures smooth transitions, minimizing pressure drop and maximizing sealing efficiency. Applications span various industries, from food processing with products like jasmine rice and chocolate chip cookies to plastics manufacturing handling nylon plastic and silicone rubber. Operating in continuous, automated environments, the valve accommodates diameters from 50 to 200 mm and withstands pressures up to 2.0 bar. Its robust construction includes an EPDM food-grade seal and options for cast aluminum or nickel-plated finishes, ensuring durability and compliance. Integration into existing systems is seamless, with ATEX-certified versions available for safety in explosive atmospheres. Maintenance is simplified with a modular design and limited components, promoting extended operational uptime.
