Ajax WaterStop ½" (DN 15) Jeweller

Wireless remotely controlled water shutoff valve

Product versions

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.

Discover future-proof hardware

Mechanical button
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.

Electric actuator
The controlling mechanism of the valve. It opens and closes the shutoff valve in response to commands from an Ajax hub. Compatible with all ball valves that comply with the ISO 5211 standard.

Mounting locker
Two locker options are available: one for quick actuator installation and removal, and another for protecting the valve against dismantling in public spaces.

Mounting platform with lever
A manual mechanism for opening or shutting off the water supply without using an Ajax app or the mechanical button. Works only when the electric actuator is removed.

RuB valve
Available in three versions: ½” (DN 15), ¾” (DN 20), or 1” (DN 25).

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 1 liter 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.

• Shuts off even stuck valves
• Works autonomously at sites with unstable or no power supply

Protected on every level

Ajax WaterStop Jeweller is designed to ensure reliable flood protection even in challenging conditions. IP66-rated1 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.

• Overheating notifications
• Overcurrent protection
• IP66-rated protection against water and dust

One-stop solid brassware

Ajax WaterStop Jeweller is available with three valve options: ½” (DN 15), ¾” (DN 20), or 1” (DN 25). These are the most common sizes for residential and commercial facilities. The device's electric actuator is also compatible with any ball valve that meets the ISO 5211 standard. So when it comes to sites with specific requirements, it's easy to integrate Ajax WaterStop Jeweller into existing water supply systems.

Easy deployment without mess and hassle

Ajax transforms the traditionally expensive, time-consuming, and dusty installation of anti-flood systems into a simple and smooth experience. Thanks to cutting-edge hardware and software, advanced capabilities are built into a compact design. Miniature Ajax water leak detectors fit easily into hard-to-reach places and require no disassembly — they can simply be placed on a horizontal surface without mounting. The wireless shutoff valve is installed directly into the existing plumbing line. Four mounting positions allow the valve to adapt to different pipe layouts.

Stable performance for years

Pre-installed batteries
No cable routing is required: Ajax WaterStop Jeweller is fully autonomous and does not rely on the 110/220 V~ power grid. Installation takes less time and effort, and the device is ready to operate for years on a single pre-installed battery set. When the battery level becomes low, Ajax apps notify users and companies in advance. The batteries are replaceable, so after up to three years of operation, an installer can simply swap them, and the device will continue to operate as usual.

• Up to 3 years of operation on pre-installed batteries
• Early low battery warnings in Ajax apps
• Replaceable CR123A batteries

External power supply
When a valve is expected to operate continuously or is installed in places with extreme temperatures, the batteries may discharge faster. In such cases, the device can be connected to a 9–12 V⎓ power supply. This eliminates frequent battery replacements and reduces service costs. The pre-installed batteries remain in place as a backup source, so a power outage won't be an issue.

• 9–12 V⎓ power supply connection
• Pre-installed batteries as a backup power source
• 9–12 V⎓ power supply unit is not included in the complete set.

Unique wireless technologies

In Ajax systems, communication between wireless devices is powered by proprietary technologies unmatched in the industry. Jeweller ensures reliable alarm and event transmission backed by encryption, frequency hopping, and outstanding energy efficiency.

• Up to 1,100 m of secure two-way radio communication in open space
• Encrypted two-way radio communication
• Instant alarm and malfunction notifications

Communication through steel and concrete

Some facilities have thick walls, metal partitions, or sheer distances that affect signal quality. Ajax range extenders are designed to increase the range of a wireless network and deliver a stable connection to a hub despite the obstacles. And by choosing the model with an Ethernet cable connector, you get an additional communication channel. А single system can accommodate up to five range extenders.

• Up to 5 range extenders within one system
• Ethernet-equipped model available
