High Conductance Ball Valves

ANCORP’s High Conductance (HC) high vacuum ball valve provides maximum conductance for large-diameter tubing in particulate-rich environments.

These valves work exceptionally well in systems that create deposition within the vacuum lines. The PTFE sealing surface is protected from direct deposition, maintaining a clean dynamic seal to prevent failure due to contamination.

With a fully ported ball and a reduced overall length two-piece 316L stainless steel body, its smooth contour maximizes heat transfer between the valve and heating components. Our engineers have designed this valve to enhance process efficiency, film uniformity, reduce downtime, and prolong system longevity.

This is accomplished through fully bored ball ports, reduced body length, smooth internal contours, a two-piece body, and a smooth profile.

High conductance ball valves are manufactured from corrosion-resistant materials to perform impressively in aggressive processes and on exhaust lines. They can be configured to be heated and insulated for temperature stability inside the valve. The valve is opened or closed manually or pneumatically by 1/4 turn, quick actuation.

The body and stem seals can be changed to meet customer-specific processes as required.
