In PID, do the two-position valves refer to HV or UV? Which representation method is more reasonable? Thank you!

The UV valve should be a two-position valve, while the HV valve is a manually controlled valve, similar to a control valve that can be adjusted to any position, but automatic control cannot be set up for it.
