solids Locking valves for bulk solids

Despite the broad range of available shut-off devices for solids it can be quite a challenge to find a suitable device for a particular set of requirements.

Requirements might be, for instance:

Pressure-resistant, dustproof and reliable

  • abrasive or poorly flowing bulk solids
  • at temperatures exceeding 200 °C
  • with high availability through long seal maintenance intervals and low-maintenance operation
  • compact design
  • preventing any escape of product or gases to the outside

As of May 2002, shut-off devices for bulk solids with operating pressures exceeding 0.5 bars are required to fulfil the new Pressure Equipment Directive 97/23/EC.

Typical shut-off devices for bulk solids:

  • Slide gate valve
  • Rotary gate valve
  • Butterfly valve
  • Chambered airlocks
  • Segmented shut-off devices



Detailed specifications can be found in the DATASHEETS
