Description
WaterStop Jeweller is a smart water shutoff valve. Operates as part of an automated water leak prevention system. Controls it in Ajax apps, through a button on the enclosure, a lever on a shutoff valve, as well as automation scenarios.
WaterStop communicates with the hub using an encrypted Jeweller radio protocol. The communication range without obstacles is up to 1,100 meters.
Runs on pre-installed batteries for up to three years. It can also be powered by a third-party power supply unit with 7.5–14 V⎓ and operating current of at least 1.8 A.
Operating principle
WaterStop Jeweller is a smart water shutoff valve with remote control. Operates as part of the Ajax system’s automated water leak prevention system.
WaterStop can be controlled from anywhere in the world where there is the Internet — Ajax apps allow checking the status and changing the position of the valve at any time.
WaterStop consists of the following blocks:
- The electric actuator controls the shutoff valve.
- The shutoff valve is an RuB valve. WaterStop is supplied with a BSP parallel threads valve in one of three sizes: ½” (DN 15, 15 mm), ¾” (DN 20, 20 mm), or 1″ (DN 25, 25 mm).
- The mount is installed between the shutoff valve and the electric actuator.
- The mounting locker fixes the electric actuator on the shutoff valve. There are two options: standard (pre-installed) and anti-sabotage (for installation in public places).
