1. Indlela yokusebenza ngokuvula okukhulu ukwandisa impilo yesevisi ivumela i-valve yokulawula umoya ukuthi isebenze ekuvuleni okuphezulu ngangokunokwenzeka, njenge-90%. Ngale ndlela, umonakalo onjenge-cavitation nokuguguleka kwenzeka ekhanda le-valve core. Njengoba i-spool ibhujiswa futhi ukugeleza kwanda, i-valve ehambisanayo ivaliwe futhi. Lokhu kuzoqhubeka nokubhubhisa nokuvala kancane kancane, ukuze yonke i-spool isetshenziswe ngokugcwele kuze kube yilapho impande kanye nokuvala indawo ye-spool yonakaliswa futhi ayikwazi ukusetshenziswa. Ngesikhathi esifanayo, igebe le-throttle yokusebenza elivula kakhulu likhulu futhi ukuguguleka kuyancipha. Lokhu kungandisa impilo ye-valve izikhathi ezingaphezu kuka-1 kuya kwezi-5 uma kuqhathaniswa nokusebenza kokuqala kwe-valve phakathi nokuvuleka okuncane. Ngokufanayo, uma isitshalo samakhemikhali sithatha le ndlela, impilo yesevisi ye-valve ye-diaphragm ye-pneumatic yanda izikhathi ezingu-2.
2.Yehlisa u-S ukwandisa ukuvulwa kokusebenza nokwandisa impilo. Indlela yokunciphisa i-S, okungukuthi, ukwandisa ukulahlekelwa kwesistimu ngaphandle kwe-valve yokulawula umoya, ukuze ukwehla kokucindezela okusatshalaliswa ku-valve kuncishiswe, ukuze kuqinisekiswe ukuthi ukugeleza kudlula i-valve yokulawula umoya, ukulungiswa kwe-pneumatic kufanele kwandiswe Ngesikhathi esifanayo, i-valve yokuvula idigri inciphisa ukwehla kwengcindezi ku-valve, okunciphisa i-cavitation nokuguguleka. Izindlela eziqondile zimi kanje: i-orifice throttling ifakwe ngemuva kwevalvu ukuze idle ukwehla kokucindezela futhi ivale ivalve yezandla exhunywe ochungechungeni lwepayipi kuze kube yilapho ivalvu elawula umoya womoya ithola ukuvuleka okusebenza kahle kakhudlwana. Kulula kakhulu, kulula futhi kuyasebenza ukwamukela le ndlela yama-valve we-pneumatic diaphragm ngendlela efanayo lapho i-valve ikhethiwe ukuze isebenze ekuvuleni okuncane ekuqaleni.
