A raft inflation valve has an elongated valve body with first and second ends, and a center bore. A cylindrical member has first and second ends slidably mounted in the center bore. A spring urges the cylindrical member towards the first end of the valve body. An arm is pivotally secured to the first end of the valve body to engage the first end of the cylinder member, and to move the cylinder member towards the second end of the valve body. A cutting element is on the second end of the cylinder member. A pressure gas filled vessel is secured to the second end of the valve body and has a gas discharge port. A seal member is on the gas discharge port of the vessel and is punctured by the cutting element when the arm moves the cylinder member towards the second end of the valve body. A space is in the center bore around the second end of the cylinder member. An annular groove is on the outside of the valve body in communication with the space. O-rings are above and below the annular groove and equal gas pressure is exerted against each O-ring. A coupling having a center bore rotatably extends over the annular groove, and has a gas outlet. A gas coupling is on the gas outlet for attachment to a gas fitting on a raft structure.
