For Reliable Operation under Demanding Conditions

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 Wedge Design prevents this. Thanks to its special wedge design with self-cleaning function, it closes and opens reliably even if there are heavy deposits on the valve seat. Due to the wedge-shaped design of the gate, possible deposits are specifically pushed off the valve seat or the gate seal to always guarantee a reliable sealing.

The 09.1 HV gate valve is fully functional at up to 1 bar differential pressure.

Already installed in thousands of demanding applications under various process conditions, the 09.1 HV gate valve with wedge design has proven its outstanding reliability. Especially in sub-fab applications, it has become the standard solution for vacuum pump isolation. Thanks to a wide range of design options, the gate valve can be easily integrated into any application.


The 09.1 HV gate valve with wedge design is available in manual and pneumatic versions. The standard voltage of the control valve is
24 VDC. For flange connections, customer-­specific flanges are possible in addition to ISO-KF, ISO-F, CF-F, ASA-LP or JIS. The standard gasket 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.
