Ajax Water Shut-Off Valve 1" (DN25) in Black
Ajax WaterStop Jeweller 1" (DN25) in Black
The Ajax WaterStop 1" (DN25) water shut-off valve automates the water supply shut-off to help minimise damage caused by leaks. It can operate automatically following a flood alarm or be controlled remotely through Ajax apps, making it a practical solution for homes, businesses and other premises where rapid action against water leaks is essential.
This model combines an electric actuator with a Bonomi DN25 (1") ball valve, suitable for hot and cold water pipes. It can work together with an Ajax flood detector, such as LeaksProtect, to automatically shut off the water when a leak is detected. WaterStop can also operate through scheduled scenarios or when the Ajax system is armed or disarmed.
WaterStop operates as part of the Ajax Jeweller wireless system and requires a compatible Ajax hub. Installation and commissioning are particularly straightforward for professional installers: simply open the Ajax app, scan the QR code and add the device to the system. In addition to remote control from a smartphone, it features a physical button on the enclosure and a mechanical lever for local valve operation without using the app.
This is not a replacement part; it is designed for new installations or extensions of compatible Ajax systems. It operates using four pre-installed CR123A batteries, providing up to 3 years of battery life, and also supports an external power supply. Combined with an Ajax alarm hub, it provides remote monitoring, automation and convenient control of the property's water supply.
