2-Way Ball Valves

ANCORP’s high vacuum ball valves consist of a body, stem, ball, and flanged end caps machined from corrosive resistant 316L stainless steel. Fluoroelastomers are used to seal the stem and end caps from the atmosphere while the Teflon® seats cold flow around the ball to isolate the process when closed. The valve is opened and closed manually or pneumatically by ¼ turn, quick actuation. The Teflon® sealing surface helps to protect it from deposition, maintaining a clean dynamic seal to prevent failure due to contamination.

 

Applications

The corrosive-resistant, fast actuating design of ANCORP’s vacuum ball valves makes them ideal for isolating reactors, traps, and scrubbers on vacuum process tools.
