Device preparation for downsizing the diameter of the pulmonary trunk. We designed and developed a self-expandable stent constructed from a single 0.22-mm nitinol wire in the shape of a conduit with a ...

Pressure regulators, more commonly known as pressure-reducing valves, keep the output pressure constant in compressed-air systems no matter how the input pressure or output flow changes. They contain ...

Maintaining valves throughout a plant’s lifetime helps to preserve optimal performance, minimize supply disruptions and ...
