High vacuum metering valves are used to control gas flows. Precise flow rate is set by adjusting the dial. Great for controlling the exact flow rate into or out of the system for:
1. adjusting the vacuum level.
2. adjusting vacuum flow speed.
3. back filling with inert gas.
4. safe and gradual release of vacuum.
5. stabilizing vacuum controlling system
