Protect facilities and reduce repair costs with the AJAX WaterStop 3/4in wireless smart valve — a fast, reliable water flow control solution designed to integrate with security and monitoring systems. When paired with an Ajax hub and leak sensors such as LeaksProtect (AJX1180010) or compatible third-party detectors, WaterStop automatically shuts off water in as little as 5 seconds after a leak alarm, preventing flooding and business interruptions.

Built for commercial and multi-site deployments, this AJAX water flow control device uses the Jeweller wireless protocol for dependable connectivity and remote management through Ajax apps. The combination of a durable 3/4in shutoff valve and a powerful electric actuator ensures precise performance, while adjustable anti-stuck cycles (up to 1 week) and manual override simplify maintenance and on-site operations. Ideal for facilities management, property monitoring, and integrated security setups, WaterStop supports automation scenarios, security mode triggers, and scheduled closures to fit your operational workflows.
