Operating components

shutoff valve

½, ¾, or 1" Bonomi shutoff valve provided.

electric actuator

Controls water supply.

mount

Installs between the shutoff valve and the electric actuator.

mounting lockers

Fix the electric actuator on the shutoff valve. There are two options: standard (pre-installed) and alternative (for installation in public access sites).

Water shut-off

shutoff valve

Fields of application

water supply

heating systems

Operating fluid

hot and cold water

non-aggressive liquids

Shutoff valve material

brass

Connection type and thread of shutoff valve

female—female

Thread size:

1/2“ (15 mm)
3/4“ (20 mm)
1“ (25 mm)

The temperature range of liquids the shutoff valve is suitable for

from 41°F to 248°F

Flange for connecting the electric actuator

mount

Made according to the ISO 5211 standard.

Lever on mount

For manual water supply shut-off in emergencies. Water supply control requires no tools.

Water shut-off

electric actuator

Torque

up to 8.5 N•m

Operating pressure

the device is designed for domestic pipelines with operating pressure up to 145 psi

Speed of water shut-off

up to 5 seconds

The value may increase due to contamination of the shutoff valve.

Remote control

device is configured and controlled via Ajax apps

Ajax apps also display the current state of the device: open/closed, battery charge status, external power supply, and communication with the hub.

Manual control

button on the electric actuator enclosure

When pressed, the shutoff valve opens/closes.

Additional features

Installation

quick dismantling and installation of the electric actuator on the flange without tools
4 installation positions of electric actuator on the flange
mounting lockers to complicate unauthorized disassembly of the electric actuator

The design allows installation, maintenance, and repair of the device in hard-to-reach places: mine, technical box, wall, etc. It is possible to replace the actuator unit without dismantling the shutoff valve. The electric actuator is removed from the valve without tools.

LED indication

The colour of the LED illumination of the Ajax logo indicates the electric actuator status.

Scenarios

Out of range temperature notification

The corresponding notifications are sent to Ajax apps when the device temperature tops 140°F and when it returns to normal.

Recommendations

The device is intended for indoor use. Contact a plumber to install the shutoff valve.

Anti-sabotage protection

Protection against spoofing

device authentication

Detection of communication failure

from 36 s

The time to detect the communication loss depends on the Jeweller (or Jeweller/Fibra) settings.

Tampering alarm

Notifies about attempts to detach the enclosure from the mount.

Mounting lockers for fastening

The kit includes two options:

Standard (pre-installed) locker — for quick fixing of the electric actuator on the shutoff valve. Easily removable for quick valve access.
Alternative locker — installed instead of the WaterStop’s standard locker. The alternative locker securely fixes the electric actuator on the valve and makes it harder to remove the electric actuator if someone tries it unauthorized.
