Features
100% viewport shielding Double-sided flange mount Del-Seal™ CF metal seal interface Actuated with bellows sealed rotary feedthrough Bakeable to 230ºC Six flange sizes
Description VPS Series viewport shutters provide quick and efficient shielding for all standard viewports. These shutters are ideally suited for service in high and ultrahigh vacuum coating applications. These swing type pivoting shutters feature a double-sided sealing design and are designed to mount between a port flange and the viewport. The shape of each shutter takes advantage of the maximum aperture of the inside of a standard port tube. The actual amount of shutter swing is dependent on the mating chamber's tube port diameter. The table below gives the maximum swing angle for each shutter when mounted on a standard Del-Seal™ flanged half nipple. To provide maximum shielding of viewports each shutter body has a step machined to match the shape and contour of the shutter's flapper plate. 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 230ºC. 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.

Insulator Seal (ISI) brand catalog and custom engineered ceramic to metal seal products are manufactured to ISO 9001:2008 standard utilizing our qualified hermetic brazing and joining processes.
