VPS Series rotary viewport shuttersprovide quick and efficient shielding for standardviewports. These shutters are ideally suited for service in high and ultrahigh vacuum coating applications. They are swing-type, pivoting shutters that are mounted between viewports and chamber port
flanges. The shape of each shutter has been designed to
maximize its aperture into a standard tubed port. The
actual amount of shutter swing will be dependent on the
mating chamber port's tube diameter.
The table below gives the maximum swing angle for
shutters mounted on Caburn-MDC half-nipples fitted with
standard CF metal seal flanges with corresponding tube
diameters. To provide maximum shielding of viewports, each
shutter body has a step machined to match the shape and
contour of the shutter's flap. Actuation of the shutter is
provided through an MDC bellows sealed rotary drive.
Improved design features include all stainless steel body
allowing for bakeout up to 230°C.A positive click-stop
action has also been added to the rotary driver that allows
for partial opening of the shutter's flapper plate between the
fully opened and fully closed positions. Shutter path must be
unobstructed during actuation as shutter mechanism can be
damaged when shutter is forced beyond a clear and
unobstructed travel path, such as smaller tube diameters.
