High Vacuum Ball Valve

The Ball Valve is a robust valve that offers straight, unimpeded flow and is less sensitive to particulate contamination than other valve types. The sealing seat for the ball wipes the ball clean as it is opened and closed providing a consistent seal making the valve especially useful in dirty vacuum applications. The A&N ball valve is specifically intended for high vacuum service. Valves are stocked in brass and 316L stainless steel in 1⁄8" to 6" tube O.D.; pipe thread or QF and LF end connections. Teflon® seats and Viton® seals are standard, however, other combinations are available on request.

Ball valves offer straight-through flow providing maximum conductance, interchangeable end connections, unobstructed ports and low initial installation and maintenance costs. Gas entrapment has been eliminated by drilling an evacuation hole in the shut-off side of the ball exposing the body cavity to either upstream or downstream pressure depending on installation.
