Operating components
Shutoff valve
½" (DN 15), ¾" (DN 20), or 1" (DN 25) RuB 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
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
NPT taper (ANSI B.1.20.1), female-to-female threads
Thread size:
- ½" (DN 15, 15 mm)
- ¾" (DN 20, 20 mm)
- 1" (DN 25, 25 mm)
Operating liquid temperature range
from -4 °F to 350 °F
Freezing of the fluid in the pipeline may severely damage the valve and electric actuator.
Mounting platform
to mount an electric actuator on a shutoff valve
Complies with the ISO 5211 standard.
Lever on mounting platform
To manually shut off the water supply without tools in case of emergencies.
Electric actuator
Torque
up to 8.5 N•m
Operating pressure
up to 145 psi
Shut-off speed
up to 7 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
Opens/closes the valve when pressed.
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
Overheating notification
The notification is sent to Ajax apps when the device temperature tops 140 °F and when it returns to normal.
Recommendations
The device is designed for indoor use only. Contact a plumber to install the shutoff valve.
Sabotage protection
Protection against spoofing
device authentication
Communication failure detection
in 36 s
The time 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 complete set includes 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⎓, from 1.8 A
The recommended parameters of the external power supply are 9–12 V⎓, 2 A. The batteries serve as a backup when an external power supply is connected. Use a round 2 × AWG22 cable with an external diameter of 3.0–3.7 mm to connect an external power supply.
