1. Coca umphezulu wokutywina weivelufa butterflykunye nokungcola kumbhobho.
2. Izibuko elingaphakathi leflange kumbhobho kufuneka lilungelelaniswe kwaye ucinezele iringi yokutywina yerabhaivalve yebhabhathanengaphandle kokusebenzisa i-gasket yokutywina.
Qaphela: Ukuba izibuko elingaphakathi leflange liyatenxa kwiringi yokutywina yerabha yevalve yebhabhathane, kuya kubakho ukuvuza kwamanzi kwisiqu sevalve okanye okunye ukuvuza kwangaphandle.
3. Ngaphambi kokuba ulungise ivalve, tshintshela ipleyiti yevalve amaxesha amaninzi ukuze uqinisekise ukuba akukho nto ye-jamming ngaphambi kokuba uqinise ngokupheleleyo i-nut yokulungisa.
Qaphela: Ukuba kukho i-jamming,ivalve yebhabhathaneayiyi kukwazi ukuvulwa ngokupheleleyo okanye ivalwe, kwaye i-valve stem iya kuguqulwa kwaye iguqulwe yi-actuator yevalve yombane okanye ye-pneumatic.
4. Kunqatshelwe ngokungqongqo ukufaka i-valve ye-butterfly uze udibanise i-flange, ngaphandle koko i-rubber yokutywina i-valve ye-butterfly iya kutshiswa.
5. Xa utshintsha indawo engezantsi yombane okanye i-pneumaticivelufa butterfly, kufuneka ihlanganiswe ukusuka kwindawo evaliweyo ukuya kwindawo evaliweyo kunye nendawo evulekileyo kwindawo evulekileyo. Emva kokuba umatshini wonke uhlengahlengiswe, ufakwe kwipayipi.
