For the Most Challenging Sub-Fab Processes

Very High proportions of by-products in the gas flow can lead to valve malfunctions as well as unplanned maintenance work due to the formation of deposits. The 09.1 HV gate valve with protection ring prevents this. Thanks to its special wedge design with self-cleaning function and to a protection ring, it closes and opens reliably even if there are heavy deposits on the valve seat. Due to the wedge-shaped design of the gate, deposits are specifically pushed off the valve seat or the gate seal to always guarantee a reliable sealing. The protection ring in addition prevents any accumulation of deposits in the plate housing by fully covering the housing in open position of the valve.
The 09.1 HV gate valve is fully functional at up to 1 bar differential pressure.
Already installed in demanding applications under various process conditions, the 09.1 HV gate valve with protection ring has proven its outstanding reliability in sub-fab applications. It can be easily integrated into any application.


Closed
Open

The 09.1 HV gate valve with protection ring is available in pneumatic versions. The standard voltage of the control valve is 24 VDC. The standard seal material is FKM, but other materials are available upon request. In addition, the integration of a soft-pump function is possible
as well as the addition of additional access points for e.g. measuring instruments.
