Ibhokisi lokushintsha umkhawulo we-valve iyithuluzi lensimu lokuma kwe-valve okuzenzakalelayo kanye nempendulo yesignali. Isetshenziselwa ukuthola nokuqapha indawo yokunyakaza kwepiston ngaphakathi kwevalve yesilinda noma enye i-cylinder actuator. Inezici zesakhiwo esihlangene, ikhwalithi ethembekile nokusebenza okuzinzile kokukhipha, futhi isetshenziswa kabanzi.
Ibhokisi lokushintshwa komkhawulo we-valve, elaziwa nangokuthi izinkomba zokuma kwe-valve, inkomba yokuqapha indawo, idivayisi yempendulo yesikhundla se-valve, ukushintshwa kwesimo se-valve, kungafakwa kuma-switch valve njenge-engeli valve, i-diaphragm valve, i-valve uvemvane, njll., ukuze kukhishwe isimo se-valve ngendlela yesignali yokushintsha, okungaba Kulula ukuxhuma ohlelweni olukusayithi lwe-PLC noma lwe-DCS ukuze uthole impendulo ekude yesimo sokushintsha i-valve.
Ucwaningo lwamadivayisi empendulo yamavalvu emazweni ahlukahlukene luyafana, kodwa kunomehluko othile kwikhwalithi yomkhiqizo kanye nenani. Amadivayisi empendulo yevalvu ngokuvamile angahlukaniswa abe abathintwayo nabangeyena ongathintwa. Iningi lamadivaysi empendulo yokuxhumana akhiwe amaswishi alinganiselwe emishini. Ngenxa yokuba khona kwezingxenye zokuthintana eziwumshini, kulula ukukhiqiza izinhlansi. Ngakho-ke, uma usebenzisa ezenzakalweni zokuvikela ukuqhuma, kuyadingeka ukufaka i-casing-proof-proof, okuyinto enzima kakhulu. Uma i-valve ihamba njalo, ukunemba nokuphila kwedivayisi yempendulo kuzokwehla. Idivayisi yempendulo okungeyena othintana naye ngokuvamile yamukela iswishi ye-NAMUR yokusondela. Nakuba inqoba ukushiyeka kwedivayisi yempendulo yokuxhumana, idinga ukusetshenziswa ngesivimbelo sokuphepha ezenzakalweni zokuvikela ukuqhuma, futhi izindleko ziphezulu.
