Ajax WaterStop [3/4] (8EU) ASP white

Ajax WaterStop Jeweller is a wireless ball valve with an electric actuator that protects a building from water damage. When Ajax LeaksProtect or another leak detector raises an alarm, the valve shuts off the water supply within 7 seconds — even with nobody on site.

The water can also be shut off and turned back on manually from the Ajax app, for example before a longer absence, or by an automation scenario at a set time. The position of the valve is always visible in the app and the events stay in the log.

WaterStop comes in three sizes: 1/2″ (DN 15), 3/4″ (DN 20) and 1″ (DN 25). The valve keeps itself serviceable with a regular open-and-close cycle, so the mechanism does not seize up even after a long idle period.
