Butterfly cheki mavharuvhuzvinosanganisira swing cheki mavharuvhu uye simudza cheki mavharuvhu.Swing cheki mavharuvhu ane hinge mechanism uye vharafu inoputika segonhi rinozorora zvakasununguka pane yakatemerwa chigaro chevharuvhu.Kuitira kuti ive nechokwadi chekuti chivharo chevhavha chinogona kusvika panzvimbo yakakodzera yechigaro chevhavha pese pese, iyo valve clack inogadzirwa mune hinge mechanism kuitira kuti clack ive nenzvimbo yakakwana yekugezera uye inobatika nechigaro chevhavha yakazara.Iyo valve clack inogona kugadzirwa zvachose nesimbi, kana simbi yakashongedzwa nedehwe, rabha, kana yekuvharisa yekugadzira, zvichienderana nekuita zvinodiwa.Kunze kwezvo, kana swing cheki vharuvhu yakavhurwa zvizere, iyo fluid pressure inenge isina kuvharika.Nokudaro, kudonha kwemhepo kuburikidza nevhavha kuduku.
 
Iyo dhisiki yevhavha yekusimudza yevhavha inowanikwa pachisimbiso chechigaro chevhavha.Kunze kwekuti dhisiki yevharuvhu inogona kusimuka nekudonha zvakasununguka, iyo yakasara yevharuvhu yakaita sevharuvhu.Mvura inomanikidza inomanikidza diski yevhavha kuti isimudzwe kubva pachisimbiso chechigaro chevharuvhu, uye kuyerera kwepakati kunokonzera kuti diski yevharuvhu idonhe zvakare pachigaro chevharuvhu uye icheke kuyerera.Pahwaro hwemamiriro ekushandisa, iyo valve clack inogona kuve yeese-simbi chimiro kana inogona kupfekedzwa nechimiro cherabha pads kana mhete dzerubha pafuremu yayo.Kufanana nemavharuvhu ekumisa, mafambiro emvura kuburikidza nevhavha yekutarisa yakamanikana.Nokudaro, kudonhedzwa kwemhepo kuburikidza nevhavhavhavha yekusimudzira yakakura kudarika iyo yevhavha yekuongorora, uye kuyerera kwevheji yekuvhara kwevhavha hakuwanzo kuderedzwa.Mavharuvhu emhando iyi achaiswa akachinjika mumapaipi.
