use a PID controller
Ideally, the valve should settle into a single position once setpoint is reached. A hunting valve over-controls, or goes too far, then reverses in an attempt to the correct overshoot, but goes too far, reverses direction again, and constantly repeats this cycle. A hunting valve results in poor control, and prematurely wears out the valve's mechanical parts. Hunting is usually indicative of loop gain too high (PID gain + process gain), or a valve that is oversized for the intended flow, or noisy input signal, or a PID integral term too small.
It does not have a heater control valve.It does not have a heater control valve.
Where is the the heater control valve??
a gate valve is a one way totally open or closed valve, a control valve is a variable valve.
Animal Control
There isn't a water control valve.
where is the heater control valve
The evap control valve is on the cannister
Overhauling a control valve means replacing all of the worn parts to bring the valve to a condition where it will be able to perform as well as it did when the valve was new.
Show me where that air valve control valve is located on a 2000 navigator
The idle air control valve on the Chevy Colorado actually controls the speed of your engine's idle. The valve is sometimes called the idle speed control valve.
