Solenoid valves for leak detection

Norway is at the forefront of the fight against water leaks in private homes and office buildings. Here, it has been a legal requirement to secure all new constructions from potential leaks since 2011. Denmark has introduced similar legal requirements in 2018 and it is likely that several other countries will be implementing similar legislation in the coming years. Insurance companies are increasingly motivating homeowners to prevent water damage by offering more affordable insurance for homes with installed water leakage control systems.

The increased focus on water leaks on the part of both authorities and insurance companies has led to digital solutions that detect water leaks immediately and shut off the water supply, thereby limiting the damage as much as possible.

The solution consists of sensors that are connected to a control system that sounds an alarm if a water leak occurs. The system then sends a signal to a shut-off valve, which automatically shuts off the water supply and ensures that no more water leaks out. The shut-off valve can be mounted either on the building's main water supply or on the water supply to the kitchen, the laundry room, the manifold cabinet, or wherever there are other installations connected to the water supply.

Fortunately, individual buildings are rarely affected by a water leak. This means that the shut-off valve is often installed on a system for a long time without ever being activated, which increases the risk of them getting stuck.

In order to avoid this problem, Danfoss, in collaboration with leading providers of water leakage solutions, has developed a valve program that, when building in the leak detection system, is activated once daily to ensure that it always works. The updated solenoid valve has already been installed in hundreds of systems in recent years and has proven to work flawlessly. The daily valve shutdown is so brief that consumers do not notice changes in the water

Danfoss continues to closely monitor developments in water leakage control and can provide customers with advice and service that are adapted to local conditions. Solenoid valves from Danfoss meet the highest quality standards and are delivered at competitive prices compared to ball valves of the same standard.

The Danfoss solenoid ECO brass solenoid valve program is available with all required drinking water approvals as RISE, SINTEF, ACS, WRAS and PZH.
