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?

The regular pump can be connected to the circuit network to enable or disable on condition. But it only lets the fluid flow one direction, and throttles the flow to 1200/s or more likely less

I would also love to have a valve instead of a pump, the flow limitation of the pump doesn't match the new fluid system and i'd rather manually connect a pipe and remove it when not needed than gimping my whole system with a pump, even legendary ones.

FWIW, the specific application can be achieved by separating your steam engines into a separate electric network and connect it to the main grid through a power switch.

This can be achieved by connecting a battery to a judgment arithmetic unit to create an SR latch, which checks whether the power is sufficient and switches on/off the fluid pump. As for the 1200 flow limit, it can be broken through by connecting multiple fluid pumps in parallel

Real-world Solenoid valves are (usually) directional flow as well. The diaphragm (B) is held-closed by the Fluid’s pressure, until the back pressure is released by activation of the Solenoid (E). Reversing the direction of flow causes pressure to build up on the wrong side of the pressure chamber (C) - closing the valve.
