We recommend first installing thevalve without the actuator into the pipeline.Tip5.1 Preparation for installationProceed as follows:The plant operator is responsible for clean-ing the pipelines in the plant.Î Check the valve to make sure it is cleanand not damaged.Î Flush and clean the pipeline thoroughlybefore installing the regulator.Any impurities carried along by the processmedium may impair the proper functioningof the regulator. We recommend installing astrainer (e.g. SAMSON Type 2 NI) upstreamof the pressure reducing valve.Î Check to make sure that the type desig-nation, valve size, material, pressure rat-ing and temperature range of the regula-tor match the plant conditions (size andpressure rating of the pipeline, mediumtemperature etc.).Î Check any mounted pressure gauges tomake sure they function.Î For steam applications, make sure thatthe pipelines are dry. Moisture will dam-age the inside of the regulator.NoteNote
