WaterStop 3/4 White
Manufacturer overview
Wireless shutoff valve with an electric actuator for remote water supply control
Not a drop of problems. Ajax WaterStop Jeweller is a smart valve designed to protect facilities from flooding. The valve automatically shuts off the water supply within 7 seconds of a leak being detected, whether by LeaksProtect Jeweller or a third-party detector. Routine water control also becomes easier: the valve can follow automation scenarios to shut off water on schedule, upon alarms, or when the system is armed or disarmed. Configuration, real-time notifications, device state, and remote water control are available in Ajax apps anytime, from anywhere in the world.
Preventing water damage with Ajax. Ajax stops leaks before they become a problem. LeaksProtect Jeweller detects leaks and triggers Ajax WaterStop Jeweller to shut off the water supply within just 7 seconds.
Wherever leaks can occur. Ajax WaterStop Jeweller helps keep homes protected around the clock, even when residents are away or asleep. Whether it's a leak under a washing machine, a dishwasher, or a damaged pipe, the valve automatically shuts off the water supply to help prevent damage and avoid costly repairs. Ajax apps provide additional peace of mind by offering real-time insights into the system.
Discover future-proof hardware. A button for manual water supply control and device operation. A short press opens or closes the valve, and a long press activates or deactivates the device.
Water shutoff in 7 seconds. Ajax WaterStop Jeweller is equipped with a powerful actuator delivering up to 8.5 N•m of torque. This is enough to shut off even a stuck valve without risking damage. Under normal operating conditions, Ajax WaterStop Jeweller shuts off the water supply within 7 seconds of receiving a command or after LeaksProtect Jeweller or a third-party sensor detects a leak. In a system with a ¾-inch pipe and 2.5 bar water pressure, less than 33 oz of water is released before shutoff. Thanks to battery-powered operation, facilities and users' peace of mind remain protected 24/7, even during a power outage.
Protected on every level. Ajax WaterStop Jeweller is designed to ensure reliable flood protection even in challenging conditions. IP66-rated 1 enclosure protects the electrical components from humidity and dust. If a valve is stuck, the device will still attempt to shut off the water supply. Should this result in overcurrent or overheating, Ajax WaterStop Jeweller will immediately send notifications via Ajax apps.
