Metal Seal Vacuum Valves
from Nor-Cal Products, Inc. - The Vacuum Experts
Leak valves are used for controlling gas introduction into high and ultra-high vacuum systems. These valves utilize an optically flat sapphire poppet and a metal seat, allowing bakeout temperatures to 450 degrees C. Valves are manually actuated by a cantilever arm with precision adjustment threads. [See More]
