KREISEL

DOME VALVE

The KREISEL DOME VALVE is a shut-off-valve especially designed for the bulk solids industry.

The advantages are on the one hand the 100% free opened cross section in opened position

and on the other hand an opening- & closing-sequence without any relative movement

between the sealing up parts like calotte / dome and inflatable sealing. The inflatable sealing

will be pressurized after finishing the closing sequence and is pressed against the Dome body.

Bulk solids particle up to 2mm diameter will be embedded into the sealing. After de-

pressurizing the particle will be freed. Additionally the KREISEL DOME VALVE is able to seal-off

high pressure differences 100% leakage free.

Characteristics

>" For leakage free Sealing-Up Of pressure Vessels as: Inlet-valve, Outlet-valve, De-dusting valve

>- For leakage free sealing-up of conveying pipes

>■ For replacement of 2-way-valves

>" 100% free cross section in opened position

>■ No sealing-up parts in the bulk solids flow

> Easy and robust design

>■ Can cut through static or moving columns of bulk solids

>■ For pressure differences up to 6bar(g) - (higher pressure differences on request)

>* Long operating life

>• Low maintenance

> Easy exchangeable inflatable sealing

>- Up to temperatures of 200°C - (higher temperatures on request)

> Perfect suitable for high abrasive bulk solids, e.g. sandy alumina, fly ash or coke
