Firstly, the tried and trusted EXKOP QV II is now also available for dust class 2 and a reduced explosion pressure (pred) of up to 2 bar. In addition, the launch of the EXKOP QV III, the new big brother of the QV II, means it is now possible to protect lines with diameters of between 300 and 600 mm. With an innovative, space-saving design, it can even be installed in confined areas where space is at a premium. Direct integration of the pressure storage tank keeps the dimensions to the minimum.
