Safety valves (100) accurately control closure and opening of fluid passage through the valve. Valves include a barrier (150) that blocks the fluid until removal only by a high-energy projectile (140). Following removal and opening, the barrier (150) or the projectile (140) can flow through the valve (100), which remains open. Bullets, pneumatic pistons, shot, coilgun pellets and any other forceful projectile (140) may impact and remove the barrier (150). The projectile (140) is actuated with any type of chemical reaction, firing pin, spring release, accelerating circuit, ignition circuit (141). Catchers (160) in the valve envelop or otherwise retain the projectile (140) or barrier pieces and enter the fluid flow of the opened valve (100) without blocking it. Disruptable barriers (150) include strong but breakable glass plates (250), thin steel sheets (350), a rotatable door (450) and other barriers that can withstand potentially over 10,000 psi (69 MPa) of fluid pressure while closing the valve (100). Valves (100) can use circuits (151) to both monitor valve open/closed status and initiate firing the projectile.
