I'm providing a slow-closing solenoid valve for a hydroelectric system in a village in the Philippines. I need to have the normally closed valve activated to open when the batteries are drained to a certain level.
The current system (without a solenoid valve) is a mile-long pipe descending from a small pond. During the operational season, it runs 24/7 and the system for bleeding off the produced energy keeps getting fried. So we are thinking the solenoid would prevent that problem and decrease wear and tear on the hydro system.
I'm out of my league here and could use some ideas asap. Thanks.
