EB 8012 EN 17Design and principle of operationActuatorsIn 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.Note:If the travel range of the actuator islarger than the travel range of thevalve, the spring assembly in the ac-tuator must be preloaded so that thetravel ranges match. See associatedactuator 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.Note:More information is available in Da-ta Sheet u T 8012.ComplianceThe Type 3241 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).Leakage classDepending on the version, the followingleakage class applies:Seal (16 on name-plate) ME, ST ME, ST PT, PKPressure balancing(18 on nameplate) – D/B –Leakage class (ac-cording to ANSI/FCI 70-2)Min. IV Min. IV VINoise emissionSAMSON is unable to make general state-ments about noise emission as it depends onthe valve version, plant facilities, and pro-cess medium. On request, SAMSON canperform calculations according toIEC 60534, Part 8-3 and Part 8-4 or VD-MA 24422 (edition 89).WARNING!Risk of hearing loss or deafness dueto loud noise.Wear hearing protection when work-ing near the valve.
