4BRVA Rotary Vane Feeders & Airlocks

The 4B series of Rotary Valves & Airlocks provides those involved in Bulk Material Handling a drop through metering valve that provides a constant volumetric feed rate.
Rotary Valves are the first option where there is limited space and controlled feeding is required of powders and granular materials from silos, bins and hoppers.
The Multi Vane Rotor provides accurate dosing and reduces leakage from cyclones and dust collectors in to low and medium pressure pneumatic conveying lines. The same drop through valve can be utilised in feeding in to pneumatic conveying lines by the simple addition of a venturi Feeding Tee.
