I suggest yes - show a complete schematic of such protection, how you think it should look like. Then you can compare prices, complexity and reliability.

Here you go. Alarm system on Integra I assume and we have 500mA of power reserve on the control panel power supply, add FD-1 detectors kitchen (between sink and dishwasher), bathrooms, laundry room, boiler room, basement, water meter area.

solenoid valve e.g. such as: https://sklep.washservice.pl/elektrozawor-kulowy-1cal-z-silownikiem-a80-lub-a82.html 12V 7 wire version.

Set the control unit to close the valve for a few seconds once a week. Check if the end positioner gave a signal that the valve is closed and open it, if the end positioner did not give a signal we send an SMS to the owner about the valve failure, on the keypad we can display information about the failure.

When flooding is detected by one of the detectors, the control panel is to close the valve until the user clears the alarm with a separate code (so that he does not do it intentionally, e.g. when disarming the alarm). When flooding is detected, the user is informed by a text message and an appropriate information on the keypad, and if the valve trimmer does not give a signal that the valve is closed, the control panel calls the numbers entered and sends text messages about this fact, activates sounders for a few seconds.

It is possible to close the valve with alarm but this must be checked as more and more devices require access to water even when no one is home.

If the battery voltage drops below 11V and the control unit has no 230V power supply, close the valve, check the cut-off and send the user an SMS about closing the valve, if the cut-off does not give a signal, we also send this information to the owner. If 230V returns and the sensors do not signal flooding we open the valve.

IMHO a 1" valve can be replaced by a 3/4" valve in most situations which will reduce costs.
There is another outstanding issue. The valve to be designed must be hygienically approved. I.e. for drinking water.
With ball valves there is no problem, because almost every valve with a red handle is ok.
With EM valves it can be different, because as a rule their purpose is different. They are fast, so their normal use is to open and close frequently, which is not the case here. 99% of the time the valve will be open.
You can try to look for an intermediate solution. I.e. a valve, e.g. a globe valve opened by a pressure actuator, the so-called three-position actuator. That is, a motor with gears where the last stage is a helical gear. Electricity is only needed to change the opening size, not the whole opening time. However, I do not know whether such a solution for drinking water is feasible at all.
Certainly such actuators are used for central heating valves and, for example, in fan coil units, but are they used anywhere else? This I do not know.

Hello
I have implemented a water shut-off via INTEGRA using a ball valve. Here there were no problems at all. There was only one problem left for me. Controlling the valve from the TSI keypad. I thought it would be useful to have a button on the keypad to cut off the water on demand. E.g. for some repair or maintenance work. I made myself a separate tab in TSI Builder, added an "Output control" widget, indicated the output that controls the valve (INT-IORS relay output). The project compiles and uploads to TSI without any problems. However, on the keypad it does not work. The button has an exclamation mark displayed. I don't know what the issue is.

I opted for an A80 7-wire drive with a 12v supply. Exactly what kind of valve they added to the kit there I don't know.

That's quite a purchase you made .

The 2N series in that shop is approved by the PZH, but they are solenoid valves with a solenoid, not ball valves.

And I have this question. I bought an Amica dishwasher but without the aquastop function. And now I'm thinking how to protect myself against flooding. I came up with this idea: use an aquastop hose with electromagnetic shut-off and connect the power supply of the solenoid valve to a common socket with the dishwasher, but not a normal socket but a wifi-controlled one. In other words, when I want to do the dishes, I will switch on the socket remotely (system here) and the power will go to both the dishwasher and the aquastop hose. When I have finished washing, I switch off the socket and I understand that the electro-valve shuts off the water supply, yes?

Well, and what valve did you use, marfik?

I'm thinking of something like this:
https://www.aliexpress.com/item/1005003775894416.html
https://cosmogate.pl/pl/strona-glowna/518-zawor-12v-34-cala-kulowy-elektrozawor-dn20.html
Can anyone confirm that I'm not erring?
I don't have an Integra yet, but it would definitely be controlled from it in the future.

If you want to build a system on a Satel, the obvious solution is a wired ball valve controlled by a 12V electric motor, e.g. as shown by e-sparks.
I also recommend watching how a motorised ball valve works, e.g. in a PROXIMA radio anti-flooding system.
There are several videos on Youtube on this subject

It is a pity that this valve is not approved for drinking water.

I'm not sure, but I may have finally found a ball valve with actuator, designed for drinking water and 12V.
https://hpcontrol.pl/elektrozawor-kulowy-1-cal-upvc-z-silownikiem-napedem-a80-lub-a83.html
I'll still try to contact them to see if they are actually approved or just the information on the website itself:

Quote:
PVC valves have high chemical resistance. It withstands the flow of most possible solutions, acids, carbohydrates or alkalis. Valves of this type are also ideal for drinking water and food.

Examples of applications:
- waste water systems
- various chemical processes
- food production
- Plant irrigation systems
- Pharmaceutical industry
- swimming pool installations
- aquaristics
- Shipbuilding and marine industry
.

There is an option for 2, 3, 4 or 7 cables, among others.
What is the difference in application, when connected to an Integra?

Topic summary

The discussion focuses on selecting the appropriate water shut-off valve type (Normally Closed - NC or Normally Open - NO) for integration with the INTEGRA control panel via the INT-IORS module, triggered by flood sensors. NC valves are favored for safety since they close automatically on power loss, preventing flooding, but require continuous power and may need a bypass for manual water supply during outages. NO valves do not consume power continuously but fail to close without power, risking flooding. An alternative recommended solution is a ball valve with an electric actuator, powered typically at 12V, which only consumes power during valve operation (opening/closing), supports manual override, and reduces energy consumption and coil heating issues common in solenoid valves. The actuator valves often include limit switches for position feedback, enabling the control panel to verify valve status and notify users of faults. Regular cycling of the valve is advised to prevent mechanical sticking. The INTEGRA system can be programmed to manage valve control, including battery-backed operation during power failures and user notifications. Valve selection must consider continuous operation capability, power consumption, manual bypass needs, and suitability for potable water. Various valve types and configurations (3, 4, or 7-wire actuators) are discussed, with emphasis on reliability, cost, and integration complexity. Practical experience highlights the importance of valve quality, installation location, and system design to ensure fail-safe flood protection in residential settings.

FAQ

TL;DR: 71 % of home-insurance water claims stem from burst hoses and fittings [Swiss Re 2022]. “Choose fail-safe, not just low-wattage” says installer adversus [Elektroda, 18826235]. Decide between an NC solenoid (fails closed) or a 12 V motorised ball valve (draws power only 10–30 s).

Why it matters: Picking the wrong valve can double energy cost, overheat coils, or leave you unprotected during black-outs.

Quick Facts

• NC solenoid power draw: 5–32 W continuous, depending on size [Elektroda, 18812664; 18827915]
• Motorised ball valve draw: 3–6 W for ≤30 s per cycle, 0 W stand-by [Elektroda, 18812099]
• Continuous-duty rating marking: ED 100 % or “Coil Class F” (*Danfoss Catalogue*)
• Satel INTEGRA high-current output capacity: 2.5 A @ 12 V (Satel Manual)
• PZH approval mandatory for potable-water valves in PL (Journal of Laws 2022/196).

Which valve type is safest for flood protection: NC, NO or motorised ball?

NC (normally-closed) solenoids default to shut when power or control fails, giving passive safety [Elektroda, 18811477]. Motorised ball valves offer similar safety if wired so the NC relay powers “close”; they add manual override and near-zero stand-by power [Elektroda, 18812669].

Do all NC solenoid coils tolerate 24/7 energising?

No. Many irrigation-style coils are rated ED 30–50 %. Continuous energising overheats them, cutting life by up to 40 % (Siemens HVAC, 2021). Always choose coils marked ED 100 % or Class F/H and test surface temperature <80 °C [Elektroda, 18812791].

How much does a typical residential NC valve restrict flow?

A ½" pilot-operated NC valve shows Kv ≈ 3 m³ h⁻¹, about 35 % lower than a same-size ball valve (Parker datasheet). Users reported pressure drop noticeable on showers [Elektroda, 18828230].

What current can INTEGRA deliver to a valve?

High-current OC outputs supply up to 2.5 A at 12 V DC (Satel Manual, p. 36), enough for a 10 W/0.8 A solenoid or a motor drive plus relays [Elektroda, 18827636].

How do I wire a 7-core A80 ball valve to INT-IORS?

Connect COM to 12 V.
Wire CLOSE to the relay’s NC contact, OPEN to the NO contact.
Link position-feedback cores to two INTEGRA zones for “valve closed/open” status [Elektroda, 18828656].

Will the system work during a power outage?

Yes—if the valve runs on 12 V and the control panel battery still holds charge. When the mains fails, the NC relay drops, INT-IORS powers CLOSE, sealing the valve within 30 s [Elektroda, 18828425]. Battery autonomy must exceed valve runtime + alarm load.

Edge case: what if the battery dies before the valve finishes closing?

The valve may stall half-open, defeating protection. Programmers set an “early-close” rule—e.g., at 11 V battery level or after 8 h of blackout—to ensure sufficient reserve [Elektroda, 18828171].

Do motorised ball valves have potable-water approvals?

Brass DN20/DN25 units with A80/A83 actuators shipped in PL often carry PZH certificate HZ/11541/19; request the PDF from the seller [Elektroda, 21549776]. Stainless UPVC versions lack this approval and suit only process water.

How often should the valve cycle to avoid seizure?

Move the ball at least once per week or every full arming of the alarm. A 3-step INTEGRA macro—activate CLOSE, wait 5 s, activate OPEN—keeps seals lubricated [Elektroda, 18826273].

What’s the cost difference over a year?

At €0.25 kWh, a 10 W NC coil costs ≈ €22/year. A ball valve drawing 5 W for 60 s per day costs €0.03/year—a 730× saving.

Can I trigger manual shut-off from a TSI keypad?

Yes. Add an “Output control” widget targeting the INT-IORS relay. Ensure output has user rights; remove the exclamation mark by assigning it to the keypad partition [Elektroda, 19119637].

Is a Wi-Fi smart plug plus AquaStop hose a good alternative?

It works, but only when the plug is ON. If Wi-Fi drops or someone forgets to arm the plug, there is zero protection [Elektroda, 20307248]. Fail-safe wiring to the alarm panel is more reliable.
