H-AR airlock
- High-duty drop through rotary valve
- 24/7 industrial applications
- Absorbing differential pressure
- Protective system up to 10 barg (St1 and St2)
Introduction
TBMA high-duty H-AR drop-through rotary valves are used for dosing powder and granular materials in 24/7 industrial processes. The H-AR valves can be used as a protective system up to 10 barg for products in dust class St1 and St2.
In combination with a blow-through or venturi adapter, the H-AR is very suitable for absorbing differential pressure in pneumatic conveying systems. The optimally constructed inlet of the valve ensures a high filling degree and large capacity with minimal air leakage.
