Rethinking Dust Valves
ATEX compliance in dust handling is often discussed in terms of labels and zones. In practice, the real challenge starts much earlier: understanding whether a dust valve can actually prevent flame and pressure propagation during an explosion.
Key engineering considerations
Parameters such as MESG, MIE and MIT define the real safety margins of a dust handling or filter system. If these are not aligned with the valve design, certification alone can create a false sense of security. Especially when a dust valve is expected to function as part of a certified Protection System, sealing quality, flame-arresting capability and pressure-shock resistance become critical engineering criteria.
Using our extensive process knowledge and vast experience in rotary valves, we have documented key engineering considerations in a technical white paper on dust valve design. The white paper explains how explosion parameters translate into concrete design choices, covering efficiency through drivetrain design, leakage control, internal ATEX Zone 20 requirements, and system-level explosion protection.
For system integrators and OEMs working with explosive dusts, this knowledge is essential for both compliance and risk mitigation. If ATEX, MESG or explosion compartmentalisation plays a role in your projects, we are happy to share the white paper.
