Karakteristik prensipal yo
1, estrikti nan mitan bride (BB): kouvèti a valv kò valv boulon, estrikti sa a se fasil antretyen valv.
2, mitan soude: kouvèti valv kò valv la adopte estrikti soude, apwopriye pou kondisyon travay presyon ki wo.
3, estrikti pwòp tèt ou-sele, apwopriye pou kondisyon presyon ki wo, bon pèfòmans sele.
4, Fòje asye chèk valv kò kanal adopte dyamèt konplè oswa dyamèt redwi, gwosè a default redwi.
5. Leve valv chèk, valv chèk boul, valv chèk balanse, elatriye.
6, kondisyon travay espesyal yo ka selon kondisyon yo nan prentan an bati-an.
