How do the air valves work?

Newport Vessels utilize Halkey Robers valve systems that are one-way valves. The simple rugged one-way valve makes inflation easy. The inner valve design allows air to flow into the hull but not out, and the outer valve cap makes the seal permanent. The plastic stem or button on the inner valve allows the boat to be deflated. Push in and turn to release the air. Make sure the plastic stem is in the "out" or "closed" position for inflation.
