Vacuum gate valves

Series 01 Mini-UHV vacuum gate valves have stainless steel bodies and Monovat sealing with only one moving part in vacuum. The thin-profile Series 12 aluminum version features the Vatlock spreading ball sealing technique that evenly distributes closing forces to create a highly reliable shock-free seal without cams. Available in sizes ranging from 16 to 1250 mm ID, these valves are offered with manual, pneumatic, or electric actuators and operate up to one million cycles between maintenance. They are available with CF, ISO, or ASA flanges and modifications to special requirements. VAT Inc., Woburn, MA; ph 617/935-1446, fax 617/935-3940.
