Ajax 3/4" (DN20) Water Shut-Off Valve – Black

Ajax WaterStop Jeweller 3/4" (DN 20) for automatic water supply control

The Ajax WaterStop 3/4" (DN20) Black allows you to remotely and automatically control the water supply through the Ajax security system. Designed to help prevent damage caused by leaks, it is an excellent solution for homes, offices and commercial premises. For comprehensive flood protection, it can be combined with an Ajax flood detector to automatically shut off the water when a leak is detected.

The Ajax WaterStop Jeweller combines an electric actuator with a 3/4" (DN20) shut-off valve. It can shut off or restore the water supply through the Ajax apps, from the button on the actuator or manually using the valve lever. Its actuator delivers up to 8.5 N·m of torque and, under normal conditions, closes the valve approximately 7 seconds after receiving the command.

WaterStop operates within the Ajax system using the Jeweller wireless communication protocol and requires a compatible Ajax hub. It is particularly suitable for installers who want to integrate water leak protection and automation into the same security system, with scenarios triggered by flood alarms, schedules or changes in security mode. It can therefore be integrated into installations based on an Ajax alarm control panel.

Suitable for controlling both cold and hot water pipes, WaterStop is powered by four replaceable CR123A batteries, providing up to approximately 3 years of operation. External power can also be used. This model is intended for new installations or compatible Ajax system extensions and is not a spare part, making it a practical choice for projects requiring automatic, remote and reliable water shut-off control.
