Gas Control / Leak Valve Vacuum Valves Datasheets

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]

Manual Right-Angle Valve -- 107 80
from Oerlikon Leybold Vacuum USA Inc.

These universal valves are ideal especially for smaller systems, where remote control is not essential. They may be also installed in larger systems, where backing pumps or condensate separators or similar units are to be cut off at longer intervals for maintenance purposes by maintenance personnel.

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]
