Mitundu yosiyanasiyana ya ma valve achitsulo opangidwa ndi chitsulo amagwiritsidwa ntchito m'minda yamalonda ndi mafakitale. Malo omwe amagwiritsidwa ntchito kwambiri pazitsulo zachitsulo ndi makina apadera a hydraulic a mapaipi otseguka. Valve yachitsulo yachitsulo iyenera kukhazikitsidwa pokhapokha malo "otseguka" kapena "otsekedwa" asinthidwa. Kupanikizika kwapaipi kwapaipi kuyenera kukhala kwakukulu kuposa mpweya wa 1 kuti muteteze kuphulika kwa valve yachipata.
Ikhoza kukhazikitsidwa pamene mapaipi sakudutsana kwathunthu. Valve yachitsulo yotayira idzakonza chitoliro pamalo amodzi ndipo "siyidzalumpha" pakachitika nyundo yamadzi.
Malinga ndi msonkhano, mankhwala akhoza kugawidwa mu mitundu iwiri: mphero valavu ndi parallel valavu. Malingana ndi cholinga cha payipi, valve ya pakhomo imayikidwa mwapadera pazochitika zilizonse.
Pachiyambi choyamba, valavu ya chipata cha wedge imayikidwa perpendicular kwa kayendetsedwe ka kayendetsedwe ka ntchito kuti atseke kutsegula kwa ndimeyi chifukwa cha kuyenda kwa chipata. Kukonzekera koteroko kudzathandiza kutseka kayendetsedwe ka ntchito nthawi yomweyo muzochitika zosayembekezereka. Kuyika kwa valavu yamtunduwu kumakhala kofala kwambiri m'mapaipi momwe njira zogwirira ntchito zamadzimadzi (makamaka madzi, nthunzi, zinthu zoyaka ndi zosakaniza zamchere) zimayenda.
Chachiwiri, valavu mu valavu imayikidwa pa payipi yofanana ndi sing'anga yomwe ikuyenda kudzera mu dongosolo. Amakhala ndi disk imodzi kapena zingapo zozungulira.
Malingana ndi makhalidwe ake, ma valve opangidwa ndi chitsulo amatha kugawidwa m'magulu awiri. Choyamba ndi chakuti pamene mawonedwe atsegulidwa kapena kutsekedwa paokha, kusuntha konse kumachitika mozungulira pang'onopang'ono.
Mtundu wachiwiri ndi pamene valavu ya chipata imayikidwa ndi tsinde la didlink lomwe silikukwera. Kukula kwa mapangidwe oyika mtundu uwu wa valve yachipata ndi yaying'ono kwambiri. Amaikidwa pamapaipi onyamula madzi, nthunzi, ndi zinthu zoyaka. Ma media awa sayenera kuyambitsa dzimbiri msanga.
Pazinthu zina zonse zofalitsa, tikulimbikitsidwa kuti muyike mankhwala okhala ndi spindle extension device.a
