Reliable Isolation Under All Conditions

The 16.2 HV Pendulum Isolation Valve provides reliable isolation performance combined with low particle count and low particle activation. The excellent particle performance is achieved by an exceptionally smooth opening and closing motion.

It is ideal for isolation requirements in harsh processes such as in evaporator and sputter applications. The 16.2 valve provides a 3-position pneumatic, single acting with closing spring or a standard pneumatic, single acting with closing spring.

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 16.2 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 16.2 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 16.2 series has proven its outstanding performance in all aspects.

3-position pneumatic

The 16.2 HV Pendulum Isolation Valve is available in aluminum, the body hard anodized or nickel-plated with standard flange connectors in ISO-F, ASA-LP and JIS. Customer-specific flanges can be integrated. Further options are ports for roughing (by-pass), venting or for gauges, heating solution as well as a window in the plate with borosilicate or sapphire glass.
