2 Principle of opertion The signl pressure p st genertes force F=p st x A on the diphrgm re A (). This force is blnced by the ctutor springs (). 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 () depends on the rrngement of the springs nd the signl pressure connection (). The stem connector () connects the ctutor stem () with the plug stem of the vlve. The djustble mechnicl trvel stop (Fig. ) is suitble for ctutors mde of sheet steel with effective diphrgm res of,, or cm². Using the trvel stop, the ctutor trvel cn be limited by up to % 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. Actutor stem retrcts (FE) The springs cuse the ctutor stem to retrct (sectionl drwings, left) when the diphrgm is relieved of pressure or when the supply ir fils.
