Nesplon 15 valves are designed to keep the end utilities of industrial gas lines safe; they’re fitted with flame arrestors and gas check valves. They can be installed directly on the inlet of automatic flaming torches used for automatic flaming or on the outlet of pressure reducers; they’re suitable for both comburent gas (oxygen) and fuel gas (propane).We recommend a full service of the Nesplon 15 valves in the case of a flashback, after 5 years from the date of installation and in any case after the time limit of 5 years plus 1 from the manufacturing date on the valve.
