I-Hydraulic ebuyiselwe emuva kwesiteshi sokuxuba ama-asphalt ngokuvamile ayithambekele ekwehlulekeni, kepha ngezikhathi ezithile kungahle kube nesigaba esingakaguquki, ukuvuza igesi, i-electromagnetic pilot valve, njll.

Uma i-hydraulic reversing valve ingashintshi isigaba ngesikhathi, iyona kakhulu ukuqeda kabi, intwasahlobo ibambeke noma ilimele, amabala owoyela noma izinsalela ezinamathele engxenyeni ye-pneumatic triplex kanye Ukubonakaliswa kwamafutha. Uma kunesidingo, amafutha noma ezinye izingxenye zingashintshwa.
Ngesikhathi sokusetshenziswa kwesikhathi eside, i-hydraulic ebuyisa emuva i-valve yesiteshi sokuxuba i-asphalt ithambekele ekulimaleni indandatho ye-valve core caring, isihlalo se-valve kanye nesango le-high-transsue, kubangela ukuvuza kwegesi eValve. Ngalesi sikhathi, indandatho yokubopha uphawu, isihlalo se-valve kanye ne-high-transsure yesango kufanele ithathelwe indawo, noma i-hydraulic reversing valve kufanele ithathelwe indawo ngesikhathi.
Ngakho-ke, ukuze unciphise ngempumelelo ukunciphisa izinga lokuhluleka kwezinsizakusebenza kwesiteshi sokuxuba asphalt, kuyadingeka ukunaka ukunakekelwa kwemishini nezingxenye.
