ATEX Rotary Valve (Airlock)
ATEX Rotary Valve (Airlock) is industrial airlock equipment that enables controlled discharge of dust, granules or particulate material accumulated in dust collection, filter, cyclone, silo and hopper systems.
This system helps reduce air leakage during material transfer, maintain system pressure and prevent disruption of the negative-pressure balance beneath filters or cyclones. Selecting the right rotary valve is critical for safe material discharge in processes with ATEX requirements.
Airtes provides project-specific selection, system integration and application support for ATEX Rotary Valve (Airlock) systems based on process type, dust characteristics, capacity needs, operating pressure, temperature, material density and site conditions.
Controlled Material Discharge
It ensures regular discharge of dust or granular material collected beneath filters, cyclones, silos and hoppers.
Airlock Function
It helps maintain system pressure and reduce unwanted air ingress and egress during material transfer.
ATEX-Compatible Selection
A rotary valve suitable for the application is selected to support safe operation in processes with combustible dust.
ATEX Rotary Valve (Airlock) Nedir?
ATEX Rotary Valve (Airlock) is a rotary-cell discharge device used to control material flow in dust collection and process systems while maintaining air-pressure balance.
Rotating rotor blades carry material from the inlet chamber to the outlet in a controlled manner. During this process, air passage through the system is limited, providing more stable operation beneath filters, cyclones or silos.
How Does an ATEX Rotary Valve (Airlock) Work?
Material enters the rotary valve housing through the upper inlet. As the rotor blades turn, dust or granules fill the rotor pockets and are carried to the lower outlet for discharge.
The close-clearance structure between rotor and housing helps reduce air leakage. This maintains system pressure, supports filter performance and makes material discharge more consistent.
Applications
- Industrial dust collection systems
- Cartridge filter and bag filter units
- Cyclone and centrifugal separator systems
- Material discharge beneath silos, hoppers and vessels
- Pneumatic conveying systems
- Micronized powder processing plants
- Food, chemical, cement, pharmaceutical, plastics and metallurgical industries
- ATEX-assessed processes with combustible dust
- Continuous dust discharge applications beneath filters
System advantages
- Ensures controlled discharge of dust and granular material.
- Helps maintain the system’s air balance.
- Supports negative-pressure conditions beneath filters and cyclones.
- Helps reduce dust accumulation by enabling continuous discharge.
- When correctly selected, supports process continuity and equipment efficiency.
- Provides an approach to safe material transfer in ATEX applications.
- Can be engineered for varying dust density, capacity and process conditions.
Selection criteria
ATEX Rotary Valve (Airlock) When selecting, material density, particle size, discharge capacity, operating pressure, process temperature, rotor volume, motor power, sealing requirements and connection dimensions must be assessed together.
In addition, in processes with combustible dust, ATEX zone classification, grounding, antistatic requirements, spark risk, wear resistance and maintenance access must be properly analysed. An incorrectly selected rotary valve can adversely affect system performance and process continuity.
Basic components
- Cast-iron or steel rotary valve housing
- Rotating rotor and rotor blades
- Inlet and outlet connection flanges
- Motor and gearbox assembly
- Sealing elements
- Bearings and bearing system
- Speed-control or level-control connection as required
- Suitable electric motor and grounding details for ATEX applications
