Flap diverter valves for pneumatic conveying
In pneumatic conveying systems, rerouting materials like powders, pellets, or granules between different discharge points can present issues with pressure drop and sealing efficiency. These challenges necessitate specialized solutions to ensure minimal operational disruptions.

Divert materials with minimal pressure drop
The VAB Flap Diverter Valve from WAMGROUP is designed to meet the demands of pneumatic conveying systems by efficiently rerouting powders, pellets, and granules from one discharge point to another. Its smooth internal surface prevents dead spots, ensuring a consistent flow. The device’s modular design and a limited number of components make it easy to maintain. Constructed from a lightweight cast aluminum alloy, the valve is both compact and durable, with a working temperature range of -20 to 80 °C and a pressure range of -0.3 to 2.0 bar. The model accommodates various actuators and features EPDM food-grade seals for added versatility.
Benefits
- Easy to use with narrow diverting angle (22.5°)
- Low pressure drop due to minimal transition effect
- Smooth internal surface prevents disruptions
- Modular design allows for simple maintenance
- Lightweight and compact for easy installation
