Mtengo woyesera pamwamba pa madzi uli ndi ma valve anayi a chipata: valavu yayikulu, ma valve awiri a mapiko, ndi valavu ya swab. Vavu ya phiko lotulukira madzi imatsegulidwa ndi kutsekedwa pogwiritsa ntchito actuator ya hydraulic. Pamwamba pa valavu ya swab pali gawo lokweza (sub) lokhala ndi cholumikizira cha ulusi. Kulumikizana kwa ulusi nthawi zambiri kumatchedwa mgwirizano wachangu. Umodzi wachangu umagwiritsidwa ntchito kulumikiza zida zothandizira kupanikizika zomwe zimafunika ngati zida zikuyenda pansi pa dzenje. Ma flowhead ena ali ndi chimango choteteza chomwe chimamangiriridwa ku block yayikulu kuti zisawonongeke ma valve panthawi yogwira ntchito. Pansi pa chozungulira chosankha pali valavu yayikulu ndi gawo la pansi. Pofuna kukweza ndikutsitsa chingwe cha drill stem test (DST), ma elevator (clamps) amamangiriridwa ku mutu wachangu.
Zipangizo zapamwamba ndi zapansi zimamangidwa ndi cholumikizira chachangu chonyamula katundu kuti zikhale zosavuta kusonkhanitsa ndi kusokoneza. Zipangizozo zimaphatikizapo chogwirira ntchito, valavu ya chipata cha swab chapamwamba, valavu yotetezeka yakutali, mzere woyenda ndi malo otulutsira mzere. Zipangizo zina zimaphatikizapo pampu yamanja kapena hydraulic control unit, njira yodulira waya mu valavu ya swab, adaputala ya waya ndi basiketi yonyamulira.
Flowhead ndiye chida chachikulu chowongolera chitsime ndikulola kuti waya ulowe, chomwe chimagwiritsidwa ntchito makamaka powongolera kuthamanga kwa pamwamba ndi kuyenda kwa madzi ndi mpweya panthawi yoyesa tsinde la kubowola, komanso chosavuta kutulutsa mapangidwewo pa nthawi yochepa kumayambiriro kwa chitsime chotseguka. Chingawonetse kuyenda kwa madzi enieni mu chitsime chopanikizika kwambiri ngati kukana kochepa kwa madzi, kosavuta kutsekeka. Ndipo tsinde la mtsinje lili ndi zida zonse zobowola kuti zigwirizane ndi zida bwino. Pamene nthawi yoyesa tsinde la kubowola, ntchito ya asidi, ntchito yosweka, ntchito yokhazikitsa simenti pa siteji, ntchito yokonzanso zinthu ingathenso kukonzedwa popanda kutulutsa chingwe, ingapangitse ntchitoyo kukhala yofanana kwambiri, kuchepetsa nthawi yogwira ntchito.
