16 EB 8026 ENDesign and principle of operationActuator stem retracts (FE)When the signal pressure is reduced or thepower supply fails, the springs move the ac-tuator stem upward, closing port A in themixing valve or port B in the diverting valve.The actuator's direction of action can be re-versed, if required. Refer to the mountingand operating instructions of the pneumaticactuator:u EB 8310‑X for Type 3271 and Type 32773.2 VersionsThe modular design allows an insulating sec-tion or bellows seal to be fitted to the stan-dard valve version.ActuatorsIn these instructions, the preferable combina-tion with a Type 3271 or Type 3277 Pneu-matic Actuator is described. The pneumaticactuator (with or without handwheel) can bereplaced by another pneumatic actuator in adifferent size, but with the same travel.Î Observe the maximum permissible actu-ator force.If the travel range of the actuator is largerthan the travel range of the valve, the springassembly in the actuator must be preloadedso that the travel ranges match. See associ-ated actuator documentation.The basic pneumatic actuator can be re-placed by a pneumatic actuator with addi-tional handwheel or by an electric actuator.3.3 Technical dataThe nameplates on the valve and actuatorprovide information on the control valve ver-sion. See section 2.1 and the actuator docu-mentation.More information is available in Data Sheetu T 8026.ComplianceThe Type 3244 Valve bears both the CE andEAC marks of conformity.Temperature rangeDepending on the version, the control valveis designed for a temperature range from–10 to +220 °C (14 to 428 °F). The use ofan insulating section or bellows seal extendsthe temperature range from –196 to+450 °C (–325 to +842 °F).Noise emissionSAMSON is unable to make general state-ments about noise emission as it depends onthe valve version, plant facilities, and pro-cess medium.TipNoteNote
