Setting the closing and opening limit

The video here explains how the trav­el stop is adjust­ed. The Gemü 654 and 653 types shown here can, for exam­ple, option­al­ly be sup­plied with an open­ing lim­it as well (vol­u­met­ric flow set­ting), which is why this set­ting is explained. If you change the diaphragm at a lat­er point in time, you must once again check and, if nec­es­sary, read­just the clos­ing and open­ing position.
