Dust-tight powder transfer for rigid and flexible IBC


Dust free powder transfer

The SoliValve® system operates on a "closed transfer" process that is superior to a split butterfly valve in terms of containment. This system eliminates the typical operator interactions with the bulk bag spout during all phases of discharging, While providing a very high level of containment.

Once the dust-tight connection between both components has been established, the active unit opens the passive closure valve to allow contained and dosed transfer of the material from an IBC or a BigBag. After partial or total discharge of the content, the active unit re closes the passive valve tightly and the receptacle can be disconnected without any dust emission.

An optional aspiration ring is available when containment is really critical. According to the tests done by one of our clients, the SoliValve®250 system is suitable for OEB 4 (1-10 ug/m3).

The SoliValve®100 has been rated for OEB 5 (<1ug/m3). A SMEPAC test report is available on request.

Advantage of a dust-tight (dust free) connection:

  • No dust cloud during filling/discharging
  • No additional de-dusting system required
  • ATEX class can be reduce because of diminished risk of ignition source, therefore it is a safer solution for the operators. In most situation, there is only an ATEX zone 20 or 21 inside the SoliValve and no ATEX zone in the room where it operates.
  • No toxic dust cloud inhaled by your operators
