Rotary Valves – TBMA

With over 50 years of experience, TBMA is an international benchmark in the design and manufacture of drop-through and blow-through rotary valves for the process industry. From hygienic and high-demand applications to heavy-duty industrial environments, TBMA offers solutions that combine continuous operation, reliability, and easy maintenance.

At Sutein, we offer a complete range of TBMA rotary valves, providing specialized technical advice to help you select the best solution for dosing, conveying, or discharging bulk solids.

H-AR Airlock

High-strength drop-through rotary valve designed for dosing powder and granular materials in continuous industrial processes (24/7).
Suitable for use with pressure differentials up to 10 barg, for products such as St1 and St2, and compatible with blow-through or venturi adapters for pneumatic conveying.
The optimized inlet guarantees a high filling degree, large capacity, and minimal air leakage.

H-GR Blowing Seal

High-strength blow-through rotary valve ideal for direct dosing in pneumatic conveying systems.
Equipped with connection flanges for easy mounting, integrated purge ports, and venting orifices designed for consistent, obstruction-free performance.

DCSR-2T Rail Valve

Designed for the dairy, food, feed, and pharmaceutical industries, where cleaning and periodic inspection are essential.
Its sliding-plate system enables fast, secure access to the interior, facilitating cleaning.
Complies with EHEDG standards and is USDA-approved for hygienic applications requiring the highest sanitary performance.

DG Quick-Clean

Rotary valves with a quick-clean system, ideal for processes requiring frequent inspection or cleaning.
Available in drop-through (H-ARQDC) or blow-through (H-GRQDC) versions.
The double-bearing design and sliding guides allow the rotor to be easily removed in either wet or dry conditions, ensuring complete safety.

H-AX Airlock

Oversized inlet rotary valves designed for low-density or compacting products.
The large opening ensures efficient discharge and filling, while round and square flanges simplify installation and reduce the number of components needed.

S-AX Dust Valve

Designed for use below dust filters or cyclones, S-AX valves operate as airlocks or explosion barriers, with differential pressures up to 500 mbar.
Manufactured in ductile cast iron (GJS-400), they can also act as secondary protection systems up to 2.5 barg, for products such as St1 and St2 dust.
