Due to gravity, the liquid phase of the medium settles at the base of the cylinder, provided the tank is upright. The gas phase is found above the surface of the liquid phase, and this makes its way into the system via the withdrawal valve and pressure regulator.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Only_for_gas_phase\"><\/span>Only for gas phase<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">The pressure regulator, hose assembly and other fittings are only <strong>approved <\/strong>for operation with the <strong>gas phase<\/strong>.

If this happens, <strong>two major problems <\/strong>may arise:<\/p>\n<ol style=\"text-align: justify;\">\n<li style=\"text-align: left;\">The liquid gas evaporates where it never should: in the pipe system or at the consumer equipment. The transition from liquid to gaseous state involves an abrupt and drastic change in volume (volume ratio of liquid to gaseous: 1 to 260). This expansion results in an <strong>increase in pressure <\/strong>and the icing of the fitting, which in turn leads to the safety devices responding to prevent overpressure (<a href=\"https:\/\/b15asa3.myrdbx.io\/en\/2016\/03\/31\/what-is-an-opso-sav-and-how-does-it-work\/\" target=\"_blank\" rel=\"noopener\">OPSO<\/a> \u2013 <a href=\"https:\/\/b15asa3.myrdbx.io\/en\/2016\/03\/31\/how-does-a-prv-pressure-relief-valve-work\/\" target=\"_blank\" rel=\"noopener\">PRV<\/a>). It can also be the case that the evaporation in the pipe system or at the consumer equipment causes <strong>possible damage <\/strong>to the appliance itself or to the environment (<a ref=\"magnificPopup\" href=\"https:\/\/b15asa3.myrdbx.io\/wp-content\/uploads\/2016\/03\/dampfdruckkurve.jpg\" target=\"_blank\" rel=\"noopener\">see vapour pressure curve<\/a>). <strong>Explosions and fire <\/strong>are probable consequences.<\/li>\n<li>There are <strong>residual substances <\/strong>in the liquid phase.
