This valve can be used to control the flow of water from a micro controller. It is normally closed type which means it is closed when not powered and any liquid will be unable to flow through it. When 12V is supplied to it, the internal valve opens and the liquid will be able to flow through it. It comes with 0.5" Threaded connector to connect pipes directly to it.
