Reliable Isolation Under All Conditions

The 01.0 Mini UHV Gate Valve series works with VAT’s patented MONOVAT technology which is specially developed to provide reliable gate sealing without any friction. With the MONOVAT technology the seal is vulcanized to the gate to provide a more reliable and durable sealing combined with superior performance in terms of low particle generation and outgassing.

The special soft closing mechanism of the MONOVAT minimizes potential shock effects to the process caused by a fast moving gate touching the valve body.

Free of lubricants, no valve mechanism in vacuum, a bake out temperature up to 250 °C and special cleaning options eliminate risks of process contamination.

With its modular design and its various design options, the 01.0 series can be tailored to nearly every requirement - even after installation - giving numerous update options, e.g. in different actuation or gates.

Already installed in thousands of demanding applications under various process conditions, the 01.0 series has proven its outstanding reliability. It has become the standard for UHV isolation in sizes from DN 16 – 50 mm (5/8" – 2").

The 01.0 Mini UHV Gate Valve is available in manual and pneumatic versions with solenoid valves either as an onboard solution or for external mounting. The solenoid valve’s standard voltage is 24 V DC but other voltages are available on request.

The valve position is indicated with a visual (mechanical) indicator. Standard options for flanges connectors are ISO-KF, CF-F. Customer specific flanges can be integrated.
The standard sealing material is FKM but other materials are available on request.

Special versions of the 01.0 for gas analysis provide bypass valves and orifice modules which are combined for a reliable and fixed pressure reduction. Window gates are also an option.
