  • Manufactured in EU

i-Flow Valve

The i-Flow valve is the latest development for inert gas fire suppression systems. Incorporating patented pressure regulating technology, building on over 20 years of innovation in clean agent alternatives to Halon.

Pressure Regulating Valve

Unlike other constant flow valves that control the pressure in the discharge pipework by varying the flow through the valve outlet, the i-Flow valve is a fully engineered pressure regulating valve. This means that should there be an unforeseen blockage in the discharge network, by a distribution valve failing to operate (creating a closed section of pipe), the i-Flow valve will close as soon as the pressure reaches 60 bar.

i-Flow systems can therefore safely use lower pressure rated manifolds, pipework and distribution valves than those required by other constant flow systems on the market.
