Passive Gate
The passive gate is a simple one-way valve that prevents gasses from flowing backwards.
The valve's input is on the side of the red circle. The valve also shows the current flow rate of the pipe when examined.
It's useful in many applications, for example:
- Preventing a pure gas from getting contaminated via a mixed gas flowing back through the pipe.
- Preventing pressure or temperature changes across two pipenets in the opposite direction.
- Quickly checking the flow rate on a pipenet without needing a gas analyzer.
