Safety instructionsGeneral safety instructions The control valves are to be mounted, started up or serviced by fully trainedand qualified personnel only, observing the accepted industry codes andpractices. Make sure employees or third persons are not exposed to anydanger.All safety instructions and warnings in these instructions, particularly thoseconcerning assembly, start-up and maintenance, must be observed. The control valves fulfil the requirements of the European PressureEquipment Directive 97/23/EC. Valves with a CE marking have adeclaration of conformity that includes information about the appliedconformity assessment procedure. The Declaration of Conformity isavailable on request. For appropriate operation, make sure that the control valves are only usedin areas where the operating pressure and temperatures do not exceed theoperating values that are based on the valve sizing data submitted in theorder.The manufacturer does not assume any responsibility for damage caused byexternal forces or any other external influence!Any hazards that could be caused in the control valves by the processmedium, the operating pressure, the signal pressure or by moving parts areto be prevented using appropriate measures. Proper shipping and appropriate storage are assumed.Note! For installation and maintenance work on the control valve, make sure therelevant section of the plant has been depressurized and, depending on theprocess medium, drained as well. If necessary, allow the control valve to cooldown or heat up to reach ambient temperature before starting any work on it. The electric actuators have been designed for use in electrical powersystems. Observe the relevant safety regulations for wiring andmaintenance. Only use power interruption devices that are protected against unintentionalreconnection of the power supply. Take special care when making adjustments on live parts. Do not removecovers!EB 5861 EN 3

Design and principle of operation1 Design and principle ofoperationThe control valves consist of the Type 3260Three-way Valve and an electric,electrohydraulic or pneumatic actuator. Forvalve sizes DN 15 to 50, the connection betweenvalve and actuator is force locking,for sizes DN 65 to 150 it is form fit.The valves are available as mixing valves ordiverting valves. The respective version ismarked by a symbol on the valve body.When used as a mixing valve, the processmedia to be mixed are fed to the ports Aand B. The combined flow is dischargedthrough port AB. For versions used as divertingvalves, the process medium entersthrough port AB, and the partial flows aredischarged at ports A and B.The position of the plug stem (6) determinesthe cross-sectional area of flow between theplug (3) and the seat (2). The plug positionis changed by the control signal acting onthe actuator. The electric actuators use athree-step signal. Actuators with an additionalpositioner can process analog signalsin the range 4 or 0 to 20 mA or 2 or 0 to10 V.The pneumatic actuators require signal pressureswith a bench range, for example, between0.2 to 1 bar or 0.4 to 2 bar, dependingon the required positioning force. Thesignal pressure is transmitted to the signalpressure connection.The Type 3372-05xx Electropneumatic Actuatorscan be actuated with analog signalsof 4 to 20 mA.1.1 VersionsType 3260/5857 · DN 15 to 25, PN 16,with Type 5857 Electric ActuatorType 3260/5824 · DN 15 to 80, PN 16,with Type 5824 Electric Actuator (DN 65and 80 with Type 5824-30 and yoke).Type 3260/2780 · DN 15 to 50, PN 16,optionally with insulating section, with Type2780-1 Pneumatic Actuator or Type 2780-2for integral positioner attachment.Type 3260/3372 · DN 65 to 80, PN 16,with Type 3372 Pneumatic Actuator.Type 3260/3374 · DN 65 to 150, PN 16,with Type 3374 Electric Actuator.Type 3260-1 · DN 65 to 150, PN 16, withyoke and Type 3271 Pneumatic Actuatorwith an effective area of 350 or 700 cm².Type 3260-4 · DN 65 to 150, PN 16, withyoke and Type 3274-11, 3274-13,3274-15 or 3274-17 Electrohydraulic Actuator.Type 3260-7 · DN 65 to 150, PN 16, withyoke and Type 3277 Pneumatic Actuator(effective area of 350 cm² or 700 cm²) forintegral positioner attachment.Note: For further details on electric or pneumaticactuators, refer to the mounting andoperating instructions:For Type 5824 EB 5824 ENFor Type 3374 EB 8331-1 ENFor Type 3274 EB 8340 ENFor Type 2780-2 EB 5840 ENFor Type 3372 EB 8313 ENFor Type 3271 EB 8310 ENFor Type 3277 EB 8311 EN6 EB 5861 EN

InstallationCaution!Install the valve free of stress and with theleast amount of vibrations as possible.Pipeline routingTo allow the control valve to work properly,the pipeline upstream and downstream ofthe valve must be straight and free of obstructionsfor a length of at least 6 times thepipe diameter (DN). Contact SAMSON ifthis length cannot be met during installation.Clean out the pipeline thoroughly prior toinstalling the valve.Make sure you choose a place of installationthat allows you to freely access the controlvalve even after the entire plant has beencompleted.Thoroughly flush the pipelines prior to installation.Install a strainer (e.g. SAMSONType 2 NI) at the respective valve inlet toprevent that any sealing parts, weld spatterand other impurities carried along by theprocess medium impair the proper functioningof the valve, above all the tight shut-off.The valve must be installed free of stress. Ifnecessary, support the piping near the connections.3.2 Strainer Install a strainer upstream of the valve inletwith the filter element vertically suspended. Remember to leave enough space to removethe filter element. Install the strainer such that the directionof flow corresponds to the arrow.3.3 Additional mountinginstructionsWe recommend to install a hand-operatedshut-off valve upstream of the strainer anddownstream of the control valve to be ableto shut down the plant for cleaning andmaintenance, and when the plant is notused for longer periods of time.12 EB 5861 EN
