KÖLLEMANN Slide-Gate-Valves have their field of application within the shutting-off and sealing off bulk-solids. To serve your demands, we offer a broad range of specialized product variants for challenging applications. The Slide-Gate-Valve acts as a lockable barrier within the vertical pipe works, which can be closed with a solid sheet-metal plate. This system is usable for any bulk-solid as well as bulk solids along with a defined moisture content. Slide-Gate-Valves are often used to encapsulate a process-room such as an combustion-chamber from a silo or other up- or downstream equipment. KÖLLEMANN Slide-Gate-Valves are designed to serve your special demands such as atmospheric sealing, bulk-solid retention, radiation heat retention or flue-gas retention just to name a few.

To optimize the operation and cost efficiency as well as to take your plants availability for energy supply into account, our slide gates can be operated by hand, electric motors and pneumatic cylinders.


Depending on the application, process-optimized extra-equipment options such as emergency-shut-off function (see further product pages), high-temperature-resistance and position-monitoring are available. In order to minimize leakages as well as any dead-space, the slide-gates can be equipped with a sealing-frame in the inlet-section along with eccentric pressurizing bolts, which ensure a maximized tightness. As a result of a long-term development, we are able to provide standard Slide-Gates for cement and rough materials as in welded-design with short delivery time and highest quality for an exceedingly competitive price.

As we produce each Slide-gate-valve fully based upon your special requirements, our sales-team is looking forward to in assisting you.
