Reliable Isolation for Standard Vacuum Processes

The 14.0 HV Gate Valve series is designed for reliable isolation in standard high cycle vacuum processes. It addresses the standard requirements of durability, modularity and serviceability with a special focus on high uptime and low cost of ownership.

The 14.0 HV Gate Valve is equipped with VATLOCK technology which is specially developed to provide reliable sealing without any friction at the gate seal. The VATLOCK mechanism also prevents valve failures thanks to the mechanical lock-in at the closed end position.

Already installed in thousands of demanding applications under various process conditions, the 14.0 has proven its outstanding reliability. It has become the standard for any high vacuum isolation requirement in sizes from DN 63 – 400mm (2.5" – 16").

With its robust and lubricant-free design, it meets all of the requirements for a reliable HV Gate Valve. Designed for an especially high number of process cycles, the 14.0 really does set the standard.

The 14.0 has various actuation and flange connection design options so it can be easily integrated into any vacuum system. A wide range of special options are available such as ports for roughing, venting or gauges, as well as alternative sealing materials to ensure optimal fit for different applications.


The 14.0 HV Gate Valve is available as manual, pneumatic and 3-position pneumatic versions with solenoid valves, either as an on-board solution or for external mounting. The solenoid valve’s standard voltage is 24 VDC but other voltages are available upon request.

The standard options for flanges connectors are ISO-F, CF-F, ASA-LP/ASA and JIS. Customer specific flanges with and without water-cooling can be integrated.
