Solenoid valve

[Walsy]

I would love to see a solenoid vale implemented for the fluid piping; a valve that doesn't allow flow until it's energized. This would have very easy use with the power switch but also unlock a lot of interesting options for people delving into circuits.

I keep finding myself in the transition between steam and solar wishing i could bank a bunch of steam using just solar power and when I expand beyond my current power requirements, flip a switch to let it through to the steam engines. Once you're more established, it would be fun to have your circuits read the current production/satisfaction levels and have the solenoids energized automatically for that extra push of power when your solar runs low

Isn't that what the pump allready does?
