Segondè pèfòmans V boul Valv
Rezime
Koupe V a gen gwo rapò reglabl ak karakteristik koule pousantaj egal, reyalize kontwòl ki estab nan presyon ak koule.
Senp estrikti, ti volim, pwa limyè, kanal koule lis.
Bay wrth gwo nwa elastik estrikti konpansasyon otomatik efektivman kontwole figi a sele nan chèz ak ploge ak reyalize bon pèfòmans sele. Plòg inik ak estrikti chèz la ka diminye mete.
Koupe V a pwodui fòs taye kwen wrth chèz la fèmen medya ki gen fib. Li espesyalman apwopriye pou louvri ak kontwole medya ki gen gwo viskozite ak medya ki gen fib ak granules.
