A pressure-reducing valve for tank blanketing
The pressure-reducing valve DM 755 (photo) has been newly developed to suit various tank-blanketing applications by offering precise control — even in the millibar range. In tank blanketing, the empty volume in the headspace of a tank is pressurized with an inert gas to prevent the undesired combination of the stored substance in the tank with atmospheric oxygen. The stainless-steel DM 755 can be used for gases and liquids at Kvs values of 0.2 to 5 m3/h in pressure ranges from 0.002 to 0.65 bars. Its compact dimensions and the new lever mechanism give the valve the greatest possible flexibility. Its modular structure combined with the matching Easy-Adapt adapters provides a wide range of connection variants on the valve, which can be precisely tailored to the user’s system. An ATEX version of the valve is in preparation. – Mankenberg GmbH, Lübeck, Germany
