Reliable Isolation Under All Conditions

The 16.8 Large HV Pendulum Isolation Valve provides reliable isolation performance also under harsh process conditions. It is ideal for isolation requirements in applications with large volume flows such as large coating or display production systems. Therefore, it is offered in DN 400 and 500mm. The 16.8 valve provides optional a 3-position pneumatic or a standard pneumatic, both double acting.
With its special split body design it allows maintenance without any disassembly of pipe connections or process chamber connections. Its slim design allows to mount the 16.8 directly to a process chamber, eliminating e.g. the volume normally required in a chamber - valve - pump connection.
With its robust design as well as a variety of design options, the 16.8 series is easy to integrate into various vacuum processes.
Already installed in hundreds of batch and inline production systems around the world under various process conditions, the 16.8 series has proven its outstanding performance in all aspects.

The 16.8 Large HV Pendulum Isolation Valve is available in aluminum with standard flange connectors in ISO-F and JIS. Customer-specific flanges can be integrated. Further options are ports for roughing (by-pass), venting or for gauges. As the 16.8 is often used to isolate turbo pumps a splinter shield grid is also available.
