A locking poppet valve that is reusable and can be pyrotechnically actuated includes an actuating mechanism and a valve assembly that are in fluid communication. A fluid channel traverses through a valve body and fluidly connects the actuating mechanism to a poppet valve positioned within the valve body. When the actuating mechanism is fired, a piston is displaced within an actuator housing, which in turn displaces hydraulic fluid within the actuator housing and the fluid channel. The displaced hydraulic fluid acts to push a valve spool along a valve stem, opening the poppet valve and allowing fluid to flow through the valve body. Additionally, the piston is held in a fired position by a locking mechanism, such that the poppet valve remains open. The poppet valve can be reset by disengaging the locking mechanism and allowing the hydraulic fluid to re-displace within the fluid channel and the actuator housing.
