ABSTRACT:
A plurality of gas actuated valves capable of high-speed action, great prure endurance and withstanding shock, vibration and a marine environment. A sliding member, closing the valves inlet ports, may be retained by a frangible flange. Electrically-initiated gas cartridges produce a rapid pressure rise causing the sliding member to be displaced thereby shearing the flange and allowing the sliding member to uncover the inlet ports for ambient fluid entry. A plurality of O-rings minimize functional sensitivity to external pressure and seal the valve against the entry of the ambient fluid.
