An actuator (100; 200; 300), comprising: a housing having a first end, a second end opposite the first end, and a bore (116; 216) defining a poppet movement axis (106; 302) disposed between the first end and the second end; a solenoid (128; 328) disposed within the bore (116; 216) and extending about the poppet movement axis (106; 302); an armature (120; 220) disposed within the bore (116; 216) and movable between an engaged position and a disengaged position, the engaged position being proximate the solenoid (128; 328), the disengaged position being spaced apart from the solenoid (128; 328); a magnet (132; 232; 332) disposed within the bore (116; 216) between the armature (120; 220) first end of the housing, the magnet (132; 232; 332) being magnetically coupled to the armature (120; 220) to bias the armature (120; 220) towards the armature disengaged position; a poppet movably disposed within the bore (116; 216) between a closed position and an open position, the open position being proximate the solenoid (128; 328) and the closed position being spaced apart from the solenoid (128; 328); a collet (126; 326) disposed within the bore (116; 216) and longitudinally overlapping the poppet along the poppet movement axis (106; 302), the collet (126; 326) being laterally movable between poppet-fixed position and a poppet-freed position; a locking ring (124; 324) disposed within the bore (116; 216) and longitudinally overlapping the collet (126; 326), the locking ring (124; 324) being movable along the poppet movement axis (106; 302) between a locked position and an unlocked position; and a striker portion disposed within the bore (116; 216) between the locking ring (124; 324) and the armature (120;220), the striker portion axially overlapping both the armature and the locking ring (124; 324) to axially displace the locking ring and allow the poppet to move along the poppet movement axis (106; 302). a housing having a first end, a second end opposite the first end, and a bore (116; 216) defining a poppet movement axis (106; 302) disposed between the first end and the second end; a solenoid (128; 328) disposed within the bore (116; 216) and extending about the poppet movement axis (106; 302); an armature (120; 220) disposed within the bore (116; 216) and movable between an engaged position and a disengaged position, the engaged position being proximate the solenoid (128; 328), the disengaged position being spaced apart from the solenoid (128; 328); a magnet (132; 232; 332) disposed within the bore (116; 216) between the armature (120; 220) first end of the housing, the magnet (132; 232; 332) being magnetically coupled to the armature (120; 220) to bias the armature (120; 220) towards the armature disengaged position; a poppet movably disposed within the bore (116; 216) between a closed position and an open position, the open position being proximate the solenoid (128; 328) and the closed position being spaced apart from the solenoid (128; 328); a collet (126; 326) disposed within the bore (116; 216) and longitudinally overlapping the poppet along the poppet movement axis (106; 302), the collet (126; 326) being laterally movable between poppet-fixed position and a poppet-freed position; a locking ring (124; 324) disposed within the bore (116; 216) and longitudinally overlapping the collet (126; 326), the locking ring (124; 324) being movable along the poppet movement axis (106; 302) between a locked position and an unlocked position; and a striker portion disposed within the bore (116; 216) between the locking ring (124; 324) and the armature (120;220), the striker portion axially overlapping both the armature and the locking ring (124; 324) to axially displace the locking ring and allow the poppet to move along the poppet movement axis (106; 302).
