WaterStop is equipped with a powerful actuator of up to 8.5 N•m torque. This is enough to shut off even a stuck-up valve without the risk of damaging it. Under normal operating conditions, WaterStop shuts off the water in 5 seconds after the command or automatically by scenario whenever LeaksProtect or a third-party sensor detects flooding. In a setting with a ¾-inch pipe and 2.5 bar of pressure in the water supply system, less than 1 liter of water will leak out.

Inside the water leak prevention system based on Ajax, every device operates either on pre-installed batteries or has a backup power supply in case of a blackout. The system monitors the facility 24/7, giving you complete peace of mind that the property is protected.

• Shuts even a stuck-up valve
• Suitable for facilities with unstable or no power supply

Protected on every level
WaterStop is suitable for controlling both hot and cold water supplies and is ready to operate in challenging environments. With additional protection, WaterStop withstands overcurrent and notifies about overheating, making it impossible for the electric actuator to fail even when the shutoff valve is stuck.

• Overheating notification
• Overcurrent protection

WaterStop is available in three versions with different valve options: ½” (DN 15), ¾” (DN 20), or 1” (DN 25). Those are the most common sizes used to cover any demand, from residential to business facilities. Also, the WaterStop electric actuator is compatible with all ball valves that meet the ISO 5211 standard. So when it comes to specific tasks and sizes, a plumber installs an available on every market compatible valve, and the installation engineer easily connects the electric actuator.

Installation without any construction involved
The myth about anti-flood systems being difficult to install is busted. Ajax minimized an expensive, long, and dusty experience for clients and professionals. Cutting-edge hardware and software engineering allowed us to implement advanced capabilities with significant autonomy in a compact size. Miniature Ajax water leak detectors suit hard-to-reach places and do not require enclosure disassembling — they can be installed on a horizontal surface without attaching. The shutoff valve is installed in line with an existing plumbing system. The actuator unit does not require wires and fits limited spaces, having four possible installation positions towards the valve.
