IntshayeleloIivalvu zeenaliti zeHikelok NV7 series non-rotating-stem ziye zamkelwe kakuhle kwaye zisetyenziswa kakhulu kumashishini ahlukeneyo kangangeminyaka emininzi. Uxinzelelo olusebenzayo lufikelela kwi-3000 psig (206 bar), ubushushu bokusebenza buqala kwi--20℉ ukuya kwi-450℉ (-28℃ ukuya kwi-232℃).
IimbonakaloUxinzelelo oluphezulu lokusebenza ukuya kuthi ga kwi-3000 psig (206 bar)Ubushushu obusebenzayo ukusuka kwi -20 ℉ ukuya kwi 450 ℉ (-28 ℃ ukuya kwi 232 ℃)Umzimba omnye owenziwe ngesixhobo esinye, uyilo lwesiqu esingajikeleziyoIsibambo sithintela izinto ezingcolisayo ukuba zingangeni kwiindawo ezisebenzayoIncam yesiqu enokutshintshwa yenza kube lula ukuyigcina ikwimeko entleIipateni ezithe tye nezinekonaIzinto ezingama-400 zentsimbi engenasici, ubhedu kunye ne-alloy
IingeneloUyilo oluncinci noluqinileyo lufumaneka kwiipateni zokuhamba ngokuthe tye kunye ne-engileIsibambo esikhuselayo sithintela ukungcola ukuba kungangeni kwiindawo zevalvu ezisebenzayoIzivalo zezihlalo ezingasemva zokhuseleko zivuleke ngokupheleleyoI-Nonrotating-stem inika ukuvalwa okuphindaphindiweyoUkurhoxa kwesiqu okufanelekileyo kukhuthaza ulawulo lokuhamba kwamanzi rhoqoI-O-ring stem seal ayifuni kulungiswaIncam yesiqu enokutshintshwa yenza kube lula ukuyigcina ikwimeko entleIvavanywe yifektri eyi-100%
