Right now it only closes if a flood sensor is tripped, but I will make a rule to cycle once in a while to exercise the valve. This valve is expensive, but still cheaper than a ready made valve. I use these in water systems that cycle repeatedly all day everyday and they hold up. Now I can shut off the water when my kids take too long in the shower lol. Or how about when your changing a faucet or other plumbing in the house, just close and open from my phone, I like it. The main reason is for flood protection.
I`m not sure what kind of flow system you need for your aquariums, but sounds like a neat project, maybe plastic valves for that.
