Ivalvu ye-butterfly ye-double eccentric, eyaziwa futhi njengenqubo yezivalvu ye-butterfly yezinkampani eziningi, ikhona kusukela kumaphuzu amaningi njengomzimba we-ivalvu, i-rhekhodi yezivalo, i-core ye-ivalvu, isiqinisekiso se-ivalvu, isicubeko se-ivalvu, isandla se-ivalvu, umqondisi we-shaft, icova, isibonisi, kanye ne-gasket yezivalo. Isimo sakhe sekhona kusukela kwe-axis ye-stem ye-ivalvu ikhona kusukela kumqondisi we-rhekhodi yezivalo kanye neqondisi we-mzimba we-ivalvu. Lo mkhiqizo we-double eccentric ukwenza i-rhekhodi yezivalo ithuthuke ngokushesha kusukela kwi-valo yezivalo emva kokuvula, ekwazi ukubuyisela kakhulu ukugqoka okungahleliwe kanye nokugqoka phakathi kwesivalo yezivalo kanye ne-valve seat.

Kuyisisekelo esikhulu kumazwe anikezelwe, izinkampani zokuphuzamiseka, ukuphuzamiseka kwezindlela, izinhlelo zokuphuzamiseka zezamanzi, izinkampani zokuphuzamiseka zezinkampani, ukusetshenziswa kwezinhlelo zokuphuzamiseka zezamanzi, kanye nokwenza izinhlelo zokuphuzamiseka zezindawo zokusebenza, kusukela kusukela kwe-ivalvu ye-butterfly ye-concentric, i-ivalvu ye-double eccentric ibalulekile kakhulu kumaphephandaba angaphansi, ikhona indlela engcono yokuphila, kanye nokunikezwa okuhle kakhulu.

Izinhlelo zezimo:

1.     Ukudizayina okuphelele, isimo esiphakathi, kuyakha ukudizayina futhi kuyakha, kanye nokunikezwa okuhle kakhulu.

2.     Isimo se-eccentric siyakuncitsha ukugqoka kwe-rhekhodi yezivalo, ikhona ukuphila kwe-ivalvu.

3.     Kugqoka ngokuphelele ngenkohlakalo, kuyakwazi ukusebenzisa emazingeni aphansi kakhulu.

4.     Ngokuthunyelwe izinto zokugqoka kwe-rhekhodi yezivalo, i-rhekhodi yezivalo, kanye ne-stem, kuyakwazi ukuba kusebenzele kumazwe anikezelwe kanye nezikhathi ezahlukene.
