The Cla-Val 181M-2 Hy-Check Valve acts as a check valve to permit flow in one direction only. When flow stops and backpressure develops, the valve closes, thus stopping return flow in AFFF systems aboard surface vessels.
Aqueous film forming foam (AFFF) systems are highly effective in marine fire suppression applications. AFFF systems employ a variety of valves with different functions to achieve timely and reliable service when it matters most.
Each of the Cla-Val products used in the AFFF is designed and manufactured to perform with fast-acting precision, playing a critical role in protecting life and equipment in the event of a fire aboard surface vessels.
