<p>A fire suppression system comprises a reservoir (2) to contain a fire suppressant material, said reservoir (2) having an outlet, at least one nozzle (11, 42) from which the suppressant is delivered. A valve (4, 45) joins the reservoir outlet and said nozzle (11, 42), said valve (4, 45) including a movable valve member (57) and a seat cooperating therewith, said valve member (57) being movable from a closed position with respect to said seat preventing communication between said reservoir (2) and said nozzle (11, 42), and an open position permitting the flow of said material from said reservoir (2) to said nozzle (11, 42). An actuator (46, 49) operatively associated with said valve (4, 45) to selectively causes movement of said valve member (57) from said closed position to said open position, and said actuator (46, 49) maintains a fluid under pressure to maintain said valve member (57) in said closed position, said actuator (46, 49) being operable to vent said fluid to lower the pressure therein and permitting said valve member (57) to move to said open position. <IMAGE></p> |
