Theserdo valveS15fofa4vbln ni serdo-hydraulic serdo valve yihariye yagenewe sisitemu ya peteroli ya EH. Ishyirwaho cyane muri moteri ya peteroli ihuriweho na Accuator. Kubera ko ibipimo ngenderwaho bya serdo byunvikana cyane kwangirika kwa lisansi, ituze rya peteroli ningirakamaro kubikorwa bisanzwe bya serdo valve.

Mubikorwa bifatika, kunanirwa kwinshi kwa serdo valve s15fofa4vbln bifitanye isano nubwiza bwamavuta. Kugirango tumenye neza imikorere ya serdo, dukeneye kuvugurura no kweza lisansi irwanya. Hano, dukoresha amavuta ya vacuum Prifier ya peteroli arwanya lifuer, ashobora gukuraho neza umwanda ukomeye mumavuta. Izi myuka ziyungurujwe kuyungurura neza no hejuru-umwanda hejuru, kugirango ibipimo ngenderwaho byamavuta arwanya lisansi yujuje ubuziranenge.

Byongeye kandi, kugirango tumenye neza amateka yamavuta arwanya lisansi, tugomba no kongeramo ibikoresho byo kuvura amavuta. Ibi bikoresho birashobora kudufasha kugenzura ingano nubunini bwa aside yamavuta yamavuta ya peteroli murwego rusanzwe, bityo bigabanya cyane urwego rwamavuta kandi twirinda kunanirwa kwa serdo.

Kunoza ibikaba neza muyungurura kandi nuburyo bwiza bwo guhangana n'umwanda wa peteroli. Kurugero, turashobora kongera ibikaba neza muyungurura kuva micrones 10 kugeza mikorobe 5. Muri ubu buryo, ndetse n'ibice bikangurura, bityo bigatuma ingano yubunini bwamavuta kandi igera ku ngaruka zo kurinda valve ya serdo.

Muri rusange, gusaba kuriserdo valveS15fofa4vBln muri sisitemu ya peteroli ya EH ifite ibisabwa byinshi kugirango ireme ryamavuta arwanya lisansi. Tugomba kwemeza ubwiza bwamavuta arwanya lisansi binyuze mu kwezwa kwanyuma, kongeramo ibikoresho byiza byo kuvura amavuta, no kuzamura ibikaba neza muyungurura ibintu, kugirango tumenye imikorere isanzwe ya serdo valve. Ibi ntibishobora kunoza gahunda ya sisitemu gusa, ariko nanone kwagura ubuzima bwa serivisi ya servo no kugabanya ibiciro byo kubungabunga.
