Introduction
TBMA high-duty H-GR blow-through rotary valves are equal to the H-AR valves and are used for direct dosing into pneumatic conveying systems in demanding, industrial applications.
The H-GR valves are equipped with connecting flanges for direct mounting to the pneumatic conveying lines on both the transport inlet as well as the transport outlet. The integrated blow-through connections are adapted to the rotor shape, ensuring that the rotor pockets are completely blown empty. The valves are also standard provided with vent holes.
