A slow leak of the first stage valve known as intermediate pressure creep can cause the interstage pressure to rise until either the next breath is drawn, or the pressure exerts more force on the second stage valve than can be resisted by the spring, and the valve opens briefly, often with a popping sound, to relieve the pressure. the frequency ...

At the time, TODAY spoke with Crum about the shark bite, which is so unlikely to happen that experts say there is a one in 11.5 million chance of a person ever experiencing something similar.
A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
While the odds of being bitten by a shark are remarkably low-1 in 4.3 million, according to the Florida Museum of Natural History-one Stuart, Florida, man has beaten those odds twice in just over ...
A shutdown valve (also referred to as SDV or emergency shutdown valve, ESV, ESD, or ESDV; or safety shutoff valve) is an actuated valve designed to stop the flow of a hazardous fluid upon the detection of a dangerous event. This provides protection against possible harm to people, equipment or the environment.
