Product maitiro
1. Ventilation butterfly valve ivhu uye inonzwisisika mukugadzira, yakasarudzika muchimiro, yakareruka muhuremu uye inokurumidza mukuvhura nekuvhara.
2. Iyo butterfly valve ine zvakanakira zvenguva diki yekushanda, kushanda kwakaringana uye smart kushanda-kuchengetedza.
3. Kushandisa zvinhu zvakakodzera kusangana netembiricha yakasiyana yepasi, yepakati nepamusoro midhiya uye corrosive media.
4. Hapana matanda ekubatanidza, mabhoti, nezvimwewo, kushanda kwakavimbika, hupenyu hurefu hwebasa, husina kukanganiswa nekuyerera kwezvinobudisa nhau.
