OMAR rotary valves are essential devices for ensuring the continuous and controlled discharge of powders from silos, hoppers, and filtration systems, compartmentalizing zones at different pressures.
Designed to minimize air losses and optimize bulk material handling, they are used in numerous industrial sectors: from powder processing to filtration, through to pneumatic conveying processes.
Rotary Valves with Rubber Blades
The traditional rotary valve with rubber blades is the ideal solution for continuous discharge under standard conditions, where good sealing and reduced probability of clogging are required.
- Flexible rubber blades – Adaptable to internal geometry to reduce air losses and improve sealing
- Robust structure – Made of painted sheet metal, wear-resistant steel, or stainless steel, depending on the application type
- Typical applications – Dust extraction and discharge systems
- Ease of maintenance – Simple design and easily replaceable components

Mechanically Sealed Rotary Valves
The mechanically sealed rotary valve is designed for more complex applications, where it is necessary to maintain high airtightness between environments at different pressures, preventing unwanted air passage.
- Precision couplings and metallic seals – Ensure excellent airtightness even under demanding conditions
- Suitable for fine powders and sensitive materials – Ideal for processes requiring accurate flow control and high efficiency
- Resistant structure – Made of painted steel or stainless steel for greater durability
- Typical applications – Industrial filtration systems, dosing plants, lines under vacuum or controlled pressure
