How might we control a 2" valve >2000ft away in a remote village. We're thinking that we power the system with a 12 v or 24 v solar powered/ battery backup. The spot in the village with line of sight to the proposed location of the array is 2000 ft. The valve is another 230 ft beyond the array and not visible from the village. The valve will divert monsoon contaminated water from the solar powered system that brings water to the village from 900 ft below. Since the valve will block the flow from the seep/ spring entering the system, there is space for the diverted stream to runoff.
Is this system going to be automated or will the valve always be operated by a person?
If it requires manual input then you may find this product useful..
This Rx can be run on 12Vdc or 24Vdc and has 4 switched outputs. Depending on the power demands of your valve you may need an external relay.
