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

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.

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.
