Hi,
so im trying to control the water flow through a 12V ball valve for a classic car heater using 4-20ma. The water flow of the engines coolant passes into the heater matrix. I would like to control the opening of the valve using a potentiometer; so as i rotate the pot the valve opens gradually and allows more or less water into the heater matrix thus giving me temperature control of the air being blown into the car. the car has a 12/14v battery.
how will this be wired?
The specs of the valve are below:
Model Number CTF001 Modulating type
Rated Voltage 12V
Working Current <200ma
Output torque MAX 6Nm
Full on off time <30s
Control Mode 4-20ma
working pressure 1mpa
power <5W
medium temperate 0-95 degrees celcius
IP 65 rated
I'm confused as to how this would be wired up and what rated pot i would use. Ive posted pics below of the valve
