AJAX Automation WaterStop Valve 3/4″

Not a drop of problems

• WaterStop automatically shuts off the water in 5 seconds at a facility with an Ajax security system if LeaksProtect or a third-party water leak detector is triggered
• The device combines a high-quality valve and a powerful electric actuator. You can control WaterStop and check its status from anywhere in the world — all you need is an Internet connection and an Ajax app
• You can also create a scenario to shut the water off at a specific time or when arming the system

• Radio communication range : up to 1,100 m (Between device and hub or radio signal range extender without obstacles)
• Radio signal encryption
• Frequency hopping : Prevents radio interference and jamming

Operating components

• Shutoff valve :  ¾" (DN 20), Bonomi Industries shutoff valve included in complete set
• Electric actuator : Opens or closes the valve
• Mounting platform : To install an electric actuator on a shutoff valve
• Mounting lockers : To fix an electric actuator on a shutoff valve.
• The complete set includes two options: : standard (pre-installed) / anti-sabotage

Water shut-off shutoff valve

•  Fields of application : water supply and heating systems
• Operating fluid : hot and cold water, non-aggressive liquids
• Material : brass
• Connection type and thread : F/F threaded
• Thread size: : ¾" (DN 20, 20 mm)
• Operating liquids' temperature range : from +5°C to +120°C
• Mounting platform : to mount an electric actuator on a shutoff valve 

Water shut-off electric actuator

• Torque : up to 8.5 N•m
• Operating pressure : up to 10 bars
• Shut-off speed : up to 5 seconds (The value may increase if the valve is clogged or stuck)
• Remote control : control and configuration in Ajax apps
• Apps provide all information about the device: current valve state (open/closed), statuses of battery charge, external power supply, and communication with a hub
• Manual control : the control button on the electric actuator enclosure 

Additional features

• Installation : does not require tools and enclosure disassembling
• 4 possible mounting positions of electric actuator towards the valve
• anti-sabotage locker to complicate unauthorized dismount of an electric actuator
• The design allows maintenance, and repair in hard-to-reach places: pipe tunnels, technical boxes, walls, etc. It is possible to replace the actuator unit without dismantling the shutoff valve.
• LED indication : The LED placed under an Ajax logo on enclosure and reports the electric actuator states
• Automation scenarios : alarm reactions / security mode change reactions / scheduled actions / temperature scenarios / humidity scenarios / CO2 level scenarios / by pressing Button / by pressing LightSwitch
• Stuck prevention : the scheduled scenario automatically opens/closes a shutoff valve. Configured in Ajax apps. The recommended periodicity is once a week.
• Overheating notification : The notification is sent to Ajax apps when the device temperature tops +60°C and when it returns to normal

Anti-sabotage protection

• Protection against spoofing : device authentication
• Communication failure detection : in 36 (The time depends on the  Jeweller/Fibra settings)
• Tampering alarm : Notifies about attempts to detach the enclosure from the mount
• Mounting lockers for fastening (two options) :
• Standard locker (pre-installed) — fixes an electric actuator on a shutoff valve Removes easily for a quick access to the valve
• Anti-sabotage locker — used instead of a standard locker. Securely fixes an electric actuator on the valve to complicate an unauthorized dismount

Power supply

• Pre-installed batteries : 4 × CR123A battery (Up to 3 years of battery life)
• Optional external power supply : 7.5–14 V⎓, up to 1.8 A
• The Recommended voltage of the power supply is 9 or 12 V⎓
• The batteries serve as a backup when external power supply is connected
