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

Re: cheap solenoid valve
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:
