Drain Closure Valves
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.
