3. Ivalve yebhabhathane yeflange enye
-Uluhlu lobubanzi: DN700-DN1000
- Inkcazo: Iivalve ze-flange enye zisebenzisa izinto ezincinci kune-double flange okanye i-lug valves, ezinciphisa iindleko zokuvelisa kunye nokunciphisa iindleko zokuthutha. Ifakwe kwi-flange yombhobho kwaye igxininiswe kwindawo.
4. Lug butterfly valve
- Uluhlu lobubanzi: DN50-DN600
- Inkcazo: Iivalve zebhabhathane zeLug (uhlobo lweLug) zifanelekile kwiinkqubo ekupheleni kombhobho okanye ezifuna ukuchithwa rhoqo. Uluhlu lwedamitha luncinci kwaye luphakathi. Ngenxa yokulinganiselwa kolwakhiwo, izicelo ezinkulu zedayamitha azixhaphakanga kangako.
5. Ivalve yebhabhathane yohlobo lwe-U
Uluhlu lweCaliber: DN100-DN1800
- Inkcazo: Iivalvu zebhabhathane ze-U zisetyenziswa kakhulu kwimibhobho yobubanzi obukhulu, njengonikezelo lwamanzi kamasipala, ukucocwa kogutyulo, njl.
| Inkcazo | Uluhlu lobungakanani obuqhelekileyo (DN) | Amanqaku aphambili |
|---|---|---|
| IValve yeButterfly yamanzi | DN15-DN600 | Ulwakhiwo olubambeneyo, olunexabiso eliphantsi, olusetyenziswa ngokubanzi kwiinkqubo zoxinzelelo oluphantsi ukuya phakathi; iisayizi ezinkulu kwiinkonzo ezingabalulekanga. |
| Lug Butterfly Valve | DN50-DN600 | Ifanelekile kwinkonzo efileyo kunye neenkqubo ezifuna ukuchithwa kwelinye icala. Ukuphatha uxinzelelo olungcono kancinci kunodidi lwamanzi. |
| Ivalufa yebhabhathane eneFlanged enye | DN700-DN1000 | Okuqhelekileyo kwiinkqubo zokungcwatywa okanye zoxinzelelo oluphantsi; ubunzima obulula kwaye kulula ukuyifaka. |
| Ivalve yebhabhathane enamaphetshana amabini | DN50-DN3000(ukuya kuthi ga kwi-DN4000 kwezinye iimeko) | Ifanelekile kuxinzelelo oluphezulu, i-diameter enkulu, kunye nezicelo ezibalulekileyo; ukusebenza kokutywina okugqwesileyo. |
| Uhlobo lwe-U-Butterfly Valve | DN50-DN1800 | Ngokuqhelekileyo i-rubber-lined okanye i-line-lined ngokupheleleyo yokumelana nokubola kwiinkonzo zeekhemikhali. |

2. Uluhlu lweCaliber yeevalvu zebhabhathane ezihlelwa ngokohlobo lwesakhiwo
1. Ivalve yebhabhathane ephakathi
Uluhlu lweCaliber: DN50-DN1200
- Inkcazo: I-valve ye-butterfly ye-Centerline (i-soft seal okanye i-elastic seal) inesakhiwo esilula, esifanelekileyo kuxinzelelo oluphantsi kunye nobushushu obuqhelekileyo beendaba, uluhlu oluphakathi, kwaye lusetyenziswa ngokubanzi kumanzi, igesi kunye nezinye iinkqubo.
2. Ivalve yebhabhathane ene-eccentric ephindwe kabini
Uluhlu lweCaliber: DN50-DN1800
- Inkcazo: Ivalve yebhabhathane ephindwe kabini inciphisa ukunxiba kwetywina ngoyilo lwe-eccentric, ifanelekile kwiinkqubo zoxinzelelo oluphantsi naphakathi, inoluhlu olubanzi lwecaliber, kwaye isetyenziswa ngokuqhelekileyo kwioli kunye negesi, imichiza kunye namanye amashishini.
3. Ivalve yebhabhathane eneeccentric ezintathu
Uluhlu lweCaliber: DN100-DN3000
- Inkcazo: Ivalve yebhabhathane ye-eccentric eccentric (itywina eliqinileyo) ilungele ubushushu obuphezulu, uxinzelelo oluphezulu kunye neemeko zokusebenza ezinzima. Inoluhlu olukhulu lwecaliber kwaye ihlala isetyenziswa kwimibhobho emikhulu yemizi-mveliso, njengamandla, i-petrochemical, njl.
| Inkcazo | Uluhlu lobungakanani obuqhelekileyo | Amanqaku aphambili |
|---|---|---|
| IValve yeButterfly ephakathi | DN40-DN1200 (ukuya kuthi ga kwi-DN2000 kwezinye iimeko) | I-Stem kunye ne-disc centerlines zihambelana ngokuthambileyo-zihleli zilungele uxinzelelo oluphantsi, izicelo eziqhelekileyo. |
| Ivalve yebhabhathane ephindwe kabini | I-DN100-DN2000 (ukuya kuthi ga kwi-DN3000) | I-Disc ikhupha ngokukhawuleza esihlalweni ekuvuleni ukunciphisa ukuguga, isetyenziswe kwiimeko zoxinzelelo oluphakathi. |
| Ivalve yebhabhathane ye-Triple Offset | I-DN100-DN3000 (ukuya kuthi ga kwi-DN4000) | Yenzelwe i-hightemp, i-high-pressure, i-zero-leakage applications, idla ngokuhlala isinyithi. |
