Stormy Lifejackets - New Hydrostatic Valve

New product testing for the hydrostatic valves. When the Inflator is lowered more than about 10cm or so in the water, then the hydrostatic valve opens and lets the water meet the water sensitive element that in turn releases a stainless steel coil spring. The spring then drives a needle into the end of the gas cylinder, which is now punctured so that the gas instantly fills the lifejacket.Total buoyancy is often reached within 4 - 5 seconds. To manually activate the inflator, just pull the handle. The gas cylinder is then punctured with a needle and the lifejacket inflates within seconds.
