Knowledge extension
Low leakage means that it cannot be determined by conventional water pressure and air pressure tests. More scientific means and precise instruments are needed to detect the small external leakage.
Valves that meet low leakage requirements have been widely used abroad. In recent years, with more and more exchanges between domestic and foreign projects, some domestic projects involving toxic media and flammable and explosive media have also begun to use low leakage valves.
