Phapang lipakeng tsa valve e bohareng le e leka-lekaneng

The overcenter valve (eo hape e bitsoang "back check valve") ke valve ea thuso ea sefofane e nang le mosebetsi oa ho hlahloba mahala. Seo ho thoeng ke karo-karolelano ea lifofane e bolela karo-karolelano pakeng tsa sebaka sa khatello ea sefofane le sebaka sa ho phalla. Karo-karolelano ena ke ea bohlokoa molemong oa khatello eo valve e ka tlohang e koetsoe ho ea ho e bulehileng ka ho feletseng, haholo-holo tlas'a likhatello tse sa tšoaneng tsa mojaro. Karo-karolelano e tlase ea sefofane e bolela phapang e kholo ea khatello ea mofofisi e hlokahalang ho bula valve ka botlalo. Ha khatello ea mojaro e ntse e eketseha, phapang e hlokahalang khatellong ea mofofisi bakeng sa likarohano tse fapaneng tsa mofofisi e ba nyane.

The counterbalance valve ke valve e sebelisetsoang ho thibela cylinder ea mojaro hore e se ke ea oa, e fana ka ts'ebetso e bonolo.
