Atex Rotary Valve

Our rotary valve has more than 50 years of experience in the application of rotary drop-through and blow-through valves in the international process industry. From high demanding hygienic to heavy industrial applications and from high-end rotary valves to simple dust locks.

Our extensive range of high quality processing equipment is suitable for handling powders and granules with proven reliability in practice in a variety of processing industries such as food, pharmaceutical, Dairy, Chemical, Petro chemical and mineral industries.


H-AR Airlock

This 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 transport systems. The optimally constructed inlet of the valve ensures a high filling degree and large capacity with minimal air leakage.

Product In Brief

•Dosing of powder and granular materials
•Absorbing differential pressure due to minimal air leakage
•Protective system up 10 barg for products in dust class St1 and St2 (optional)
•Suitable for 24/7 industrial applications
•Outboard bearings, dust tight and sealed for life
•Differential pressure 1,5 barg
•ATEX 2014/34/EU certified (optional)
•Sanitary execution conforming to EHEDG guidelines for dairy and food industry (optional)


DG Quick-Clean valve

TBMA DG Quick-Clean rotary valves are specially designed for processes where frequent cleaning and inspection are required. The type DG valves are available in both drop-through (H-ARDG) as well as blow-through (H-GRDG) version.

– Easy inspection and cleaning
– Self-seeking shaft
– Minimal chance of damage

Product In Brief

S-AX dust valve

S-AX dust valves are specially designed to be used under dust filters and cyclones. Applications with a differential pressure up to 500 mbar where the valve primarily functions as an airlock or explosion barrier. The S-AX can be used as a protective system up to 2,5 barg for products in dust class St1 and St2. (optional)

These airlocks are made from GN40 nodular cast iron. This type of cast iron material is stronger and much less brittle than conventional cast iron, making it more resistant to shock loads, and has a high corrosion resistance

Product In Brief

•Light and compact dust valve
•For differential pressure up to 500 mbarg and easy to process products
•Body and covers made from high-tech GN40 nodular cast iron
•Outboard bearing, dust-tight and sealed for life
•Protective system up to 2,5 barg for products in dust class St1 and St2 (optional)
•ATEX 2014/34/EU certified (optional)
