Drop-through rotary valve for powder and granular material feeding

Achieve precise control in discharging and feeding powdery and granular materials with rotary valve technology, designed to integrate seamlessly into high-speed production lines and enhance efficiency and reliability.

Controls Discharging and Feeding of Bulk Materials

The Drop-Through Rotary Valves RV/RVR from WAMGROUP are engineered for accurate and efficient handling of powdery and granular materials across various industries. Featuring robust cast iron or stainless steel construction, these rotary valves are designed with a horizontally mounted rotor equipped with V-shaped compartments for precise material flow regulation. With feed rates ranging from 2.2 to 19.5 liters per revolution, they cater to diverse applications including concrete production, animal feed processing, and chemical manufacturing. Integrated easily into existing systems thanks to WAM standard flanges, they support working temperatures from -30 to 150°C and withstand differential pressures up to 0.2 bar. The valves are available with different drive options for tailored rotation speeds and can be customized with ATEX-certified versions for explosion-prone environments. Their ease of access simplifies maintenance, ensuring long-term reliability in continuous or high-speed operations.
