4 Principle of opertion The signl pressure p st genertes force F=p st x A on the diphrgm re A (2). This force is blnced by the ctutor springs (4). Tking into ccount the rted trvel, the number of springs nd their compression determine the bench rnge. The trvel H is proportionl to the signl pressure p st. The operting direction of the ctutor stem (7) depends on the rrngement of the springs nd the signl pressure connection (). The stem connector (8) connects the ctutor stem (7) with the plug stem of the vlve. The djustble mechnicl trvel stop (Fig. 4) is suitble for ctutors mde of sheet steel with effective diphrgm res of 20, 240, 350 or 700 cm². Using the trvel stop, the ctutor trvel cn be limited by up to 50 % in both directions (ctutor stem extends or retrcts) nd permnently djusted. Actutors re vilble with the following fil-sfe ctions: Actutor stem extends (FA) The springs cuse the ctutor stem to move to the lower end position (sectionl drwings, right) when the diphrgm is relieved of pressure or when the supply ir fils.

20 Design nd principle of opertion Design nd principle of opertion The ctutors re designed for ttchment to Series V 200 Vlves (Type 332, Type 3323, Type 353, Type 3535, Type 324 (DN 65 to 00) nd Type 3260 (DN 65 nd 80). The ctutors bsiclly consist of two diphrgm cses, rolling diphrgm nd springs. The electropneumtic ctutors re dditionlly equipped with n i/p converter nd pneumtic control system for control opertion. For ctutors with fil-sfe position "Actutor stem extends", the converter nd the control system re mounted in the lower diphrgm cse, nd for versions "Actutor stem retrcts", in the upper diphrgm cse. The signl pressure cretes force which cts on the diphrgm. The springs instlled in the diphrgm chmber oppose this force, thus ensuring compenstion. When the signl pressure fils, the springs instlled either in the top or bottom diphrgm chmber determine the ctutor s operting direction nd fil-sfe position. Actutor stem extends: Upon signl pressure filure, the ctutor stem extends nd closes the vlve (globe vlve). Actutor stem retrcts: Upon signl pressure filure, the ctutor stem retrcts nd opens the vlve (globe vlve). Electropneumtic ctutors The electric control signl issued by the controller s reference vrible rnging from 4 to 20 ma is trnsmitted to the i/p converter where it is converted into proportionl pressure signl. The pressure signl cretes force tht cts on the mesuring diphrgm (). This force is then compred with the force of the mesuring spring (3). The movement of the mesuring diphrgm is trnsmitted vi the lever (2) to the force switch (5), nd finlly corresponding signl pressure is produced. Chnges in the input signl or the vlve position cuse chnge in the ctutor stem position, corresponding to the reference vrible.

23 Attchment to vlve 2 Attchment to vlve Note! Pressurize ctutors with fil-sfe position "Actutor stem extends" before ttching them to vlve to llow the ctutor stem to retrct slightly. Should no signl pressure or, for electropneumtic ctutors, should lso no electric control signl be vilble during the mounting procedure, tighten the hexgon nut (6) ginst the force of the preloded springs using hexgonl wrench with width cross flts SW 36. Cution! Under no circumstnces must the rod nuts of the rod-type yoke be unscrewed. Actutors with fil-sfe position "Actutor stem retrcts" only require to be pressurized for ttching the stem connector. The reson for this is tht in three-wy vlves, for exmple, the plug stem might not rech the ctutor stem fter being pulled out of the vlve body. If this is the cse, the top diphrgm chmber must be pressurized until the plug stem nd ctutor stem come into contct so tht the stem connector cn be mounted. For electropneumtic ctutors, signl pressure cn be pplied to the pressure guge connection, however, the stopper (8.7, Fig. 3 top) must be removed first. Attchment using signl pressure or ma control signl. For the pneumtic ctutor, pply pressure of pprox. 3 br to the lterl signl pressure connection (8.5) locted t the bottom diphrgm chmber. For the electropneumtic ctutor, pply pressure of pprox. 3 br to the "Supply" connection nd dditionlly connect control signl of pprox. 0 ma to retrct the ctutor stem. 2. Remove the hexgon nut (6) from the vlve bonnet nd plce the ctutor with its stem retrcted by mens of the signl pressure on the vlve bonnet. 3. Mke sure the ctutor is in the proper position nd secure the hexgon nut (SW 36) pplying tightening torque of min. 50 Nm. 4. Pull up plug stem (3) until it contcts the ctutor stem. 5.
