Modular in design, our stainless steel 304/316 drain closure valves stop 99.9% of the flow of pollutants and firewater from escaping site via surface water drains & pipes thanks to its patented design and engineering success to date. Unlike penstock valves, our Flapstopper™ Drain Closure Valve stops the flow dead, specific to containing pollution & firewater run-off.
Powered by compressed air, our pollution & firewater containment valves automatically close typically in under 10 seconds from local and remote activation from a push of a button or triggered via oil/PH interceptors, sprinklers, fire alarm systems, sensors, existing BMS/SCADA systems and more.
The Flapstopper™ Drain Closure System can be supplied with additional features such as remote activation via our cyber secure & reliable radio telemetry on and off-site, also known as the “Call Point”; SMS text status alerts; custom cloud dashboard valve status & email alerts using iOS/Android devices & desktop using a web browser.
All Flapstopper™ Drain Closure Systems use either a 12v battery back-up with either a 230v to 12v dc plug or 100Ahr battery back-up with 60w/120w solar panel as part of our floor standing GRP kiosk range.
Our automated inlet & off-seat mounted Flapstopper™ drain closure valves are retrofittable and designed to fit inlet pipes from 100mm to 600mm diameter as standard. For CAD drawings, or further technical information please contact us.
