VAT Inc., of Woburn, Massachusetts, has introduced a new series of stainless steel high vacuum gate valves. These valves are designed for high vacuum pump isolation, substrate transfer and various other vacuum applications. The VAT Series 11.0 HV Gate Valve features a rugged stainless steel body with minimized flange to flange thickness allowing for maximum conductance and easy system integration, including retrofit applications. The VATLOCK gate mechanism minimizes operating shock and is mechanically locked in the closed position. These valves are designed for 200,000 cycles before first service. They are offered in both manual and pneumatic actuation and come standard with a position indicator. They are available in sizes ranging from DN63 to 320mm with the choice of ISO, ASA, CF, JIS or customer specific flanges.
