I'm looking for a valve that will shut the water off during a no-power situation. Is this the correct valve?

Yes, but you should consider your flow requirements when the valve is open. It's only a 3/4" valve, so there could be unacceptable pressure drop with high flow rates such as if you use it to control water to your entire house. The supplier may be able to provide a chart of pressure drop vs flow rate, or another Amazon user may have insight into this. My application doesn't require high flow.

This valve is normally close (when you energized it the valve open). I use it for water system and it works good.

Not really valve lasted 1 week at most. Had to replace with another brand. Valve MUST be reliable or major problems could arise.

These valves aren't designed to be energized for long periods. They generate quite a bit of heat when energized. The normally closed position will definitely shut off water in a no power situation but if you want the valve to be open at all times unless the power goes out, you should probably look for a different product as this will quickly burn out.

Yes this should work for your application. The valve is closed when there is no power. It only opens when power is supplied to the solenoid.

Yes, this item will shut off automatically when the water runs out. So it could be used in night and you don't need to worry about it.

any position will probably work, it will let water flow from holding tank, but will only allow water to flow the same as you unplugging tank

Neil, if you are talking about the Water turn off valve, no. That is a separate item.

Valve in your case should be normally open. When the valve has power the valve is closed. You want a N/O valve. The normal state of the valve is when there is no power. Flip your argument.

It uses a spring loaded valve with what might be called an egg timer. When the timer counts down to zero the valve shuts. There is no external power required.

I would say it is. This is what I used it for also. The city shut off valve. Was long enough that there was no trouble turning the key. Found no flimsiness of the key. Just too bad one end didn't have a hook on it to use to help pull the cover off the meter. Otherwise, no problems.

I would consider a small water pump on the hot supply at the waterheater. A plumber will need to help, as the return is on the cold water line. It uses very little electric power, (25-30 watts) and can be timed to turn on and off.

When you disconnect an accessory using the quick connect, it does not stop the flow of water. Attaching an accessory such as a spray nozzle will stop the flow. You can do what I do and connect a Dramm Heavy-Duty shut off valve to the end of the hose and then attach the quick connect to that which easily allows you to turn on and off the flow of water. I just checked and that shutoff valve is not nearly as cheap as they were when I ordered mine. The Dramm watering wands include the brass shutoff and they work well if you're looking to water plants or gently wash a vehicle. I hope this helps!

You'll need another piece to have a shutoff valve. This alone is just a straight flow. I found something decent at Lowes to accompany it, but the shower action on this piece is phenomenal. Highly recommend.

It SHOULD work. I know the valves open even when the water is turned off (like when we have had a couple days rain) so if you have enough pressure to push water now without a timer adding one shouldn't change anything.

The one I got was not a heavy duty brass valve, it was a black plastic cutoff valve but I have never had any problems with it leaking or shutting off

The valve on the one I bought leaked. I would use a sealed battery which is maintenance free and worry free.

I didn't like the heat so I cheated.I used a 10,000uF capacitor in parallel with ~10 ohms in series with the 12V and valve.This allows the full 12V available to pull in the valve, but then drops the current by around half, reducing the power to ~1/2 of normal.I was afraid to let the valve operate for more the about ~15 minutes with 12V.Do a net search for fast relay operation or reducing relay power consumption for some examples.Good luckTerry

Their is no alarm built into the switchYou could possible add an alarm thru a contact block. This is a 16 volt switch that simply breaks the connection if water is presentThe switch is designed for shuting down a furnace or AC unit if water is present. I have mine connected to a motorized valve that shut off my city water if water is present Good luck

The valve is normaly close. Electro magnt holds it open when it get the signal from the timer. The valve is spring loaded. Good chance it will work ok as long as no calcium deposit prev3nt it from working freely.if the source of water is faitly free from minirals, i ould try it.

Yes, it will shut off automatically when it runs out of water, even with power connected.
