In conjunction, WITT has also released a smaller version, the AV619. The device blows unwanted pressure from 5 to 500 mbar. By comparison, standard valves corresponding to the Pressure Equipment Directive 97/23/EEC often respond after an overpressure a hundred times greater.

The German manufacturer WITT Gasetechnik has released the new AV919 with a previously unavailable performance spectrum.

In conjunction, WITT has also released a smaller version, the AV619. The device blows unwanted pressure from 5 to 500 mbar. By comparison, standard valves corresponding to the Pressure Equipment Directive 97/23/EEC often respond after an overpressure a hundred times greater.

According to WITT, the new AV919 also masters these low setting pressures, while keeping a blow-off volume ten times greater at 967 m³/h under control. The opening pressure of the new development, still very compact despite being around 90 x 170 mm larger, is set precisely at the factory. Furthermore, weighing 1.5kg, the device can be used with all technical gases in temperatures ranging from -40 to +300 °C.
