Honestly you'll be hard pressed to find a decent solenoid valve that will be lighter and cheaper than something running from a $10 five gram servo. The benefit of solenoid valves is that they'll run for decades, which isn't a major issue here. A rotor valve running from a servo would be not too bad to fabricate from telescoping tubing, and you could keep the whole thing under 15 grams without any trouble.
