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. Tight-closing function: The electropneumtic ctutor is either fully vented or fully pressurized whenever the reference vrible exceeds or flls below certin preset vlue. Type 3372: "Actutor stem extends" includes switch-off function tht is ctivted when the switching point of 4.08 ma is not reched. The ctutor will be fully vented. In globe vlves, the ctutor springs will close the vlve. In three-wy vlves, port B is closed when the vlve is used for mixing service nd port A is closed when the vlve is used for diverting service. Type 3372: "Actutor stem retrcts" includes switch-on function tht is ctivted when the switching point of 9.92 ma is exceeded. The ctutor will be pressurized, cusing globe vlve to close tightly. In three-wy vlves, port B is closed when the vlve is used for mixing service nd port A is closed when the vlve is used for diverting service. 4 EB 833 EN

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. Attch the stem connector pieces to ech stem nd screw tight using the fstening screws. EB 833 EN 7

The customry mle connections for metl pipes or plstic hoses cn be used. Importnt! The supply ir must be dry, oil nd dust free. You re required to strictly observe the mintennce instructions for up - strem reducing sttions. Thoroughly purge the ir pipes prior to instlltion. The required supply pressure depends on the bench rnge nd the operting direction (fil-sfe position) of the ctutor. The bench rnge is written on the nmeplte, the operting direction is indicted by FA or FE, or by the respective symbol. Pneumtic ctutor: For "Actutor stem extends", connect the signl pressure to the bottom diphrgm chmber nd for "Actutor stem retrcts" to the top diphrgm chmber. The connection not used must be seled with vent plug. Electropneumtic ctutor: Connect the supply ir to the "Supply" connection. Actutor stem extends (FA): (Types 3372-x5x nd 3372-x53x Actutors) Fil-sfe position "Vlve closed" (for globe nd ngle vlves) Required supply pressure = upper bench rnge vlue + 0.5 br.

Checking djusting zero nd spn 4 Checking djusting zero nd spn (Electropneumtic ctutor only) Note! Mke djustments on the mounted vlve only! Zero nd spn re djusted to determine the strting point nd the upper rnge vlue of the ctutor. When the control signl (reference vrible) issued by the controller chnges from 4 to 20 ma, the control vlve must correspondingly pss through its entire trvel rnge from 0 to 00 %. Zero djustment is lwys bsed on the closed position of the control vlve. Assuming globe vlve (closed fil-sfe position) combined with Type 3372-(0/)5 or 3372-(0/)53 Actutor with fil-sfe position "Actutor stem extends", zero (strting point) must be djusted to 4 ma nd the upper rnge vlue to 20 ma. Wheres ssuming globe vlve (open filsfe position) combined with Type 3372- (0/)52 or Type 3372-(0/)54 Actutor with fil-sfe position "Actutor stem retrcts", zero must be djusted to 20 ma nd the upper rnge vlue to 4 ma. We recommend, however, tht you check zero fter the ctutor hs been ttched to the vlve. Proceed s described below:. Connect n mmeter to the control signl input nd pply compressed ir to the "Supply" input. 2. Loosen the fstening screw nd push the cover plte (8.9) side. 3. Pull the jumper from the pins to dectivte the tight-closing function. Zero is djusted on the djuster (4) nd the upper rnge vlue on the potentiometer for spn (0.). Importnt! Any spn djustment results in shift of zero. Therefore, the zero point must be redjusted fter spn djustment. Importnt!

Checking djusting zero nd spn 4. Adjusting ctutors with fil-sfe position "Actutor stem extends" Zero point (strting point). Use n mmeter to djust the input signl to 4 ma. 2. Turn zero djuster (4) until the plug stem just begins to move from its rest position. 3. Switch off the input signl nd then slowly increse it gin. Check if the plug stem begins to move t 4 (+0.) ma. 4. Correct ny devitions vi the zero djuster (4). Turning clockwise cuses the vlve to leve its rest position erlier, wheres turning counterclockwise delys the vlve leving its rest position. Upper rnge vlue 5. After you hve djusted the strting point, use the mmeter to increse the input signl to 20 ma. When reching the upper rnge vlue of 20 (-0.) ma, the plug stem must hve pssed through its entire rted trvel rnge of 00 %. 6. Adjust the potentiometer for spn (0.) until the upper rnge vlue is correct. Turning clockwise increses the trvel, turning counterclockwise reduces the trvel. 7. After correction, switch off the input signl nd slowly increse it gin. First check the strting point (4 ma), then the upper rnge vlue (20 ma). 8. Repet the correction procedure until both vlues re correct. 9. Plug jumper on the pins gin to ctivte the tight-closing function. Potentiometer for spn (0.)

Remove the protective cp nd turn the zero djuster (4) until the plug stem just begins to move from its rest position. 3. Increse the input signl nd slowly reduce it gin to 20 ma. Check if the plug stem begins to move t 20 ma. 4. Correct ny devitions vi the zero djuster (4). Turning counterclockwise cuses the vlve to move from its rest position with dely, wheres turning clockwise cuses the vlve to move erlier. Upper rnge vlue 5. Hving completed djustment of the strting point, use the mmeter to djust the input signl to 4 ma. After hving reched the upper rnge vlue of 4 ma, the plug stem must pss through its entire rted trvel rnge of 00 %. 6 Adjust the potentiometer for spn (0.) until the upper rnge vlue is correct. Turning clockwise increses the trvel, nd turning counterclockwise reduces the trvel. 7. After correction, increse the input signl gin. First check the strting point (20 ma), then the upper rnge vlue (4 ma). 8. Put the protective cp bck over the zero djuster. 9. Plug the jumper on the pins gin to ctivte the tight-closing function.

Activting nd dectivting the tight-closing function 5 Activting nd dectivting the tight-closing function The electronic switch-off nd switch-on system integrted in the ctutor ensures tight closing of the control vlve whenever the switching point is exceeded or not reched. Actutor stem extends: Should the electric control signl (reference vrible) fll below the switching point of 4.08 ma ± 0.09 ma differentil gp, the ctutor will be fully vented to close connected globe vlve. Actutor stem retrcts: Should the electric control signl (reference vrible) exceed the switching point of 9.92 ma ± 0.09 ma differentil gp, the pneumtic output will be fully pressurized to close connected globe vlve. The tight-closing function will be ctivted when the jumper is plugged in. Removing the jumper dectivtes this function. 6 Version with limit switch - djustment. Loosen stem connectors on the vlve nd exchnge front connector for clmped connector (from the ccessories). 2. Move the control vlve to the switching position in which the contct is to be mde. 3. Position clmping plte on the rod-type yoke nd shift plte until the lever rests on the stem connector clmp. Align clmping plte nd screw tight. 4. Estblish electricl connection ccording to the lbel on the clmping plte s follows: Blck (BK)/blue (BU) > contct open nd blck (BK)/brown (BN) > contct mde (closed). 5. Go below nd exceed the desired switching position. Use the djustment screw to set the exct switching point. Lever Adjustment screw Fig. 7 Limit switch EB 833 EN 3
