Karakteristik teknik
Avantaj nan tiyo asye fòje pòtay
1. Ti likid rezistans.
2. Fòs ekstèn ki nesesè pou ouvèti ak fèmti piti.
3. Direksyon koule nan mwayen an pa limite.
4. Lè konplètman louvri, sifas la sele se mwens erode pa mwayen k ap travay la pase valv la sispann.
5. Fòm kò a se relativman senp, ak pwosesis la Distribisyon se pi bon.
Dezavantaj nan tiyo asye fòje pòtay
1. Tou de dimansyon ekstèn yo ak wotè ouvèti yo relativman gwo.Pi gwo espas nesesè pou enstalasyon.
2. Pandan pwosesis la ouvèti ak fèmti, gen friksyon relatif ant sifas yo sele, ki fasil lakòz reyur.
3. fòje tiyo asye pòtay jeneralman gen de sifas poze sele, ki ajoute kèk difikilte nan pwosesis, fanm k'ap pile ak antretyen.
