Butterfly Valve Vacuum Valves
from Nor-Cal Products, Inc. - The Vacuum Experts
Quarter-turn actuation, small footprint and the shortest possible gas path make manual butterfly valves the preferred choice for many applications. O-ring sealed plate and stem provide a low-cost alternative to bellows sealed gate valves. Manual butterfly valves have a vacuum range of 1x10-9 Torr. [See More]

The VS series valves are butterfly-type valves. A circular valve plate with a sealing ring on the circumference rotates around an axis at right angle to the valve axis. As a result, the valves leave virtually the entire cross section free, offering very good conductance. The valve bodies are made of... [See More]

The QSB quarter swing valves are compact, quick acting, high conductance isolation valves. The QSB valves have a polished, stainless steel, ISO flanged body with fluoroelastomer 'O' ring sealed valve plate and shaft. The valve plate 'O' ring groove is vented to help maintain a stable high vacuum. [See More]
