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
- Drehklappen
- Kammerschleusen
- Segmentverschlüsse
Slide Gate Types FSH-FSP-FSE
Dust tight locking of powdery to granular bulk solids, with different flange dimensions, as a emergency valve, f.e. for maintenance and as a process valve, measurement fabrication.
Dust Tight Slide Gates
Dust tight and pressure tight locking of bulk solids with pneumatic activated hollow sectioning sealing, measurement fabrication.
Pivoting Shutter Type SSP
Pressure tight locking valve for pressure-/vacuum-hoppers, pipelines or reactors, free passage when open, shutting disc is not leaving the housing when open/close position.
Chamber Valve Type DSP
Lock out and dosing out of a pressure-/vacuum-system or lock in f.e. into a reactor, filling and discharge discontinously, interlock for gases and vapours.
Flap Valve Types DKP-DKH
Dust tight, pressure tight and vacuum tight locking valve for silos, hoppers and pipelines, special design for bulk solids, simple and low-cost design, low height, easy to dismantle and to maintain.
solids Disc valve Type DKA-Hygienic
Special design for bulk solids,
Hygienic Design acc. to EHEDG-Guidelines
Segment Locking Valves Type BPP
Locking valve under silos and hoppers for lumpy products, reliable design, large sections.
