2 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 is proportionl to the signl pressure p st. The operting direction of the ctutor stem (7) depends on the rrngement of the springs. The stem connector (8) connects the ctutor stem (7) with the plug stem of the vlve. Fig. shows the side-mounted Type 27 nd-operted Actutor for ctutors with effective diphrgm res of 400 nd 2800 cm² nd mximum trvel of up to 80 mm. The hndwheel (2) is fixed to the worm-gered shft (20) nd moves the ctutor stem over the worm-gered wheel (2) nd the threded bushing (22). A side-mounted hndwheel s illustrted in Fig. 4 is vilble for vlves with 20 mm trvel. The djustble mechnicl trvel stop (Fig. ) is suitble for ctutor version s well s 2800 cm² ctutors nd tndem ctutors. The ctutor trvel cn be limited by up to 50 % in both directions (ctutor stem extends or retrcts) nd permnently djusted. The tndem ctutor (Fig. 7) contins two coupled diphrgms; they produce positioning force tht is twice s high s the force of single ctutor.
