I’ve never seen it written this way; could it be intended to express cascade control of flow rate and liquid level?

The fault remains in place, and the valve closes once the air supply is exhausted. It should come with a gas storage tank.

Shut off the valve in case of fault, with a valve-shutoff indication.
