Abstract
The present invention is directed to valves for use in controlling the flow of fluid and, more particularly, to a triggerable passive valve for use in controlling the flow of fluid. In one embodiment, a fluid delivery channel is connected to a flow restrictor and a passive valve positioned in the fluid delivery channel downstream from the flow restrictor. The first passive valve prevents fluid from moving through the channel when the pressure exerted by the fluid on the first passive valve is below the burst pressure. A pneumatic actuator actuates the valve by forcing fluid through the passive valve.
