Note: Install a strainer (e.g. SAMSONType 2 N/2 NI) upstream of the regulator toprevent sealing particles, welding spatter orother impurities carried along by the processmedium from impairing the proper function-ing of the valve, especially tight shut-off.2.1 Mounting positionSee Fig. 3 for permissible mounting positions.Standard mounting position · Install valvewithout actuator in a horizontal pipeline withthe connection for the actuator facing down-wards. Make sure the medium flows throughthe valve in the direction indicated by the ar-row. Then connect the actuator to the valveusing the coupling nut (11).NOTICEProtect the regulator when it is used to controlfreezing process media.On shutting down the plant in areas not freefrom frost, depressurize and empty the regu-lator and remove it from the pipeline.2.2 Control line, equalizing tankand needle valveControl line · After mounting the actuator,fasten the supplied high-pressure control lineto the regulator as shown in Figs. 1 and 2.Control line kit · A control line kit for tappingpressure directly at the valve body is avail-able as an accessory from SAMSON. Refer toData Sheet T 3095 EN.Equalizing tank · An equalizing tank is re-quired for liquids above 150 °C and forsteam. For the control line, install the equaliz-ing tank directly downstream of the pressuretapping point at the valve. The mounting posi-tion of the equalizing tank is indicated by anadhesive label on the tank itself as well as byan arrow and the word "top" stamped ontothe top of the tank. Adhere to the mountingposition and distances prescribed, otherwisethe safe functioning of the regulator cannotbe guaranteed.Needle valve · If the regulator tends to hunt,we recommend installing a SAMSON needlevalve in the control line routed on site at theactuator connection.EB 3015 EN 7InstallationFig. 3 · Permissible mounting positions– All versions in DN 15 to 80and up to max. 80 °C– Standard mounting position– all versions –– Above 80 °C,steam applications– Only versions with fixedplug guide andup to max. 80 °C
