Flapstopper Control Panel



Installation time can be just a few hours in the case of the pollution & firewater control valve with all mounted control panels.


The pollution & firewater containment system can be mains (230V), solar or battery-powered, where the control panel or kiosk is mounted above ground in the vicinity of the chamber (no further than 30m) and simple air hoses run into the chamber via slits cut into hard surfaces, eliminating the need for deep 18in (50cm) deep trenches as would be this case if mains were required.


The basic Flapstopper pollution & firewater control panel is push button activated, normally via two push buttons located on the outside of the control wall box or kiosk. The kiosk or wall box can also be upgraded to include a wireless receiver and remote activation call points, where the output from the call points receiver is wired in parallel with the pushbutton. Please note that we do not recommend remote opening via call points, but only closing for safety reasons as this could cause a hazard to operators.

Our Flapstopper pollution & firewater containment system controls are low voltage, and each valve is supplied with its own control panel that controls the open and close sequence, plus provides feedback to a local Sites BMS or a remote dashboard of the cloud via telemetry.


Each pollution & firewater containment system includes a failsafe mechanical latch which when the unit is closed prevents the valve from opening in the event of air pressure loss. This feature is key to the widespread adoption of the Flapstopper on COMAH sites, where it is quite feasible during a fire or explosion that the control panel could be damaged or lost.


Our pollution & firewater containment control panels are a cost-effective solution for valves located within close range of one another, for example, 3 x 150mm valves can run off from one control panel.
