Almost certainly requires high pressure in one direction to make the valve open. Not really useful for vacuum.

It does not look pilot actuated. It might work. There are electric solenoid valves with kf fittings, I have one in KF16.

Advises works in zero differential pressure.
This also as advises in the sticker:
