Yep, you're looking for a 5-2 valve. Solenoid-actuated 5-2's are commonly used in FRC because you're usually working with double-acting cylinders, which require two inputs.
It has 5 ports:
- Pressure in
- Pressure out A
- Pressure out B
- Exhaust A
- Exhaust B
And two positions:
- Port A pressurized, Port B exhausted.
- Port B pressurized, Port A exhausted.
You could also get away with a 4-2 (the exhausts for A and B are combined instead of separate ports.)
The 5-2 might be more useful than the 4-2 though, as the individual exhaust ports allow you to add two needle valves (or
needle-exhausts, McMaster calls them "Flow Control Mufflers") so you can control how quickly (or slowly) each of the muscles actuates.
If you're looking for a hand-operated one, just add that to your search.
Good ol' McMaster has a pretty good selection
