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 atmosphere while the PTFE 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. PTFE sealing surface helps to protect it from deposition, maintaining a clean dynamic seal to prevent failure due to contamination.
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.
