Applications - Ideally suited for pure gases for high purity applications to put vessels under pressure and for leak detection and purge of pipe work. - Used in combination with a switch over board for the regulation of the emergency source during maintenance on the principal source. This avoids installing some extension and reducing the amount of leaking points. KEY FEATURES - Adjustable outlet pressure - Possible to connect 2 gas cylinders and a gas for purging operation (up to 3 cylinders without any extension - without using the purge line). - Ready to install with all components pre-mounted on a board. - Connectable to an alarm box using contact gauges. - Equipped with a 1/4 turn shut-off valve on the outlet. - Collection tube available on the relief valve and purge outlet. - Downstream regulation system can be decompressed by turning the hand wheel counter-clockwise.
