EB 2549 EN 5Process medium and scope of application2 Process medium and scope of applicationPressure regulator for liquids, gases and vapors up to 350 °CFor controlling the upstream pressure p1 to the adjusted set point. The valve opens when theupstream pressure rises. The upstream pressure is transmitted to the actuator over a control linethat must be installed on site.The pressure regulators are not shut-off devices guaranteeing tight shut-off. When closed, theseregulators can have a leakage rate of ≤ 0.05 % of the KVS coefficient.Overpressure protection must be installed in the plant.WARNING!Risk of injury and property damage due to high pressure in the plant.A suitable overpressure protection must be installed on site in the plant section.2.1 Transportation and storageThe regulator must be carefully handled, transported and stored. Protect the excess pressurevalve against adverse influences, such as dirt, moisture or frost, during storage and transpor-tation.When regulators are too heavy to be lifted by hand, fasten the lifting sling at a suitable placeon the valve body.WARNING!Incorrectly attached lifting slings or supports.Risk of injury and property damage due to valve falling.Securely fasten slings or supports to the valve body and secure against slipping.
