- Stuthings UHVGVB series compact gate valve is an ultra-high vacuum type compact gate valve.
The UHVGVB series compact gate valve is powered by compressed air. By changing the cylinder piston rod to push (pull) the valve core assembly to make linear motion, it controls the opening or closing of the valve plate, thereby cutting off or connecting the air flow in the vacuum system.
This series of gate valves are made of stainless steel, equipped with CF flange as standard, and can be used in various ultra-high vacuum applications.
This series of gate valves is suitable for scenarios where the working medium is air and non-corrosive gases, and is equipped with a proximity switch.
Optional configurations include different drive methods, materials, and flange options, all designed to provide better solutions for the vacuum industry.
