Variable Leak Valve
from Agilent Vacuum Technologies

The Agilent Variable Leak Valve includes a movable piston with an optically flat sapphire that meets a captured metal gasket. This forms a seal completely free from friction, seizing, and shear. The sapphire ’s movement is controlled through a threaded shaft-and-lever mechanism that provides a... [See More]

  • Type: Leak
  • Leak Rate: 1.00E-10
Vacuum Lock / Sealing Valve
from Leybold USA Inc.

Vacuum technology puts great demands on the functioning and reliability of the valves. The demands are fulfilled only if correct shut-off devices are installed for each application, depending on the method of construction, method of operation, and size. Moreover, in the construction and operation of... [See More]

Leak Valve
from Nor-Cal Products, Inc.

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]

Small Hand Operated Gas Inlet Valve -- VGL

VG style gas inlet valves are small, hand-operated valves for admitting gases into a vacuum system. By rotating a knurled screw cap, the valve stem is raised from the valve seat. Thus gas enters at a controlled flow rate from the line connected to the gas inlet. The vacuum and atmospheric sides of... [See More]
