Description

The Ajax WaterStop [1] (8EU) ASP White is a water shutoff valve with an electric actuator, built on a 1" DN 25 brass valve. It is used in water supply and heating systems with hot and cold water and non-aggressive liquids. The valve has NPT taper (ANSI B.1.20.1) female-to-female threads.

The actuator communicates wirelessly over the Jeweller protocol from Ajax and is controlled and configured in Ajax apps. It runs on 4 × CR123A batteries, and an optional external power supply of 7.5–14 V⎓, from 1.8 A, can also be used. A lever on the mounting platform allows the water supply to be shut off manually without tools in an emergency.

Key features:

  • Closes in up to 7 seconds, with a torque of up to 8.5 N•m and an operating pressure of up to 145 psi
  • Jeweller wireless connection with a range of up to 1100 m (3608.9 ft), block encryption with a floating key and device authentication
  • Manual control with the button on the actuator enclosure, and remote control and configuration in Ajax apps
  • Automation scenarios: alarm reactions, security mode change reactions, scheduled actions, temperature, humidity and CO 2 level scenarios, and control by pressing Button or LightSwitch
  • Installation without tools or enclosure disassembling, with 4 possible mounting positions of the actuator towards the valve and an anti-sabotage locker against unauthorized dismount
  • Battery life of up to 3 yr, tamper protection and detection of lost connection in 36 s
  • IP66 protection, operating temperature of 0 … +60 °C (32 … 140 °F) and operating humidity of up to 95%
